fatal python error (pygame parachute) Segmentation Fault when using Tkinter

I made small game in pygame and python 2.7 and added submit box with Tkinter.
It worked fine till I compiled it with py2exe / pygame2exe.
Compilation was error-free.
But when i clicked on exe file to launch the application, compiled-code threw this error:
fatal python error (pygame parachute) Segmentation Fault
This application has terminated in unusal way for more
information contact application support team.
When I delete Tkinter code and compile it it runs fine.
This is a part of Tkinter code:
#i tried importing both with import Tkinter and from Tkinter import*
if event.key==pygame.K_s:
subbox=Tkinter.Tk()
subbox_label=Tkinter.Label(subbox,text="Type your name:")
subbox_label.pack()
subbox_entry=Tkinter.Entry(subbox)
subbox_entry.pack()
def savescore(a):
a=str(a)
print a
print subbox_entry.get()
player_name=subbox_entry.get()
player_score=a
subbox_button=Tkinter.Button(text="Click",command=lambda:savescore(score))
subbox_button.pack()
subbox.mainloop()
UPDATE:
I kicked out Tkinter code line by line and it came up that importing Tkinter causes error!
That means that if I have just:
import Tkinter
my game won't work!!! What should I do?

Did you check py2exe/Bugs?
While it is not exactly the same crash, the root-cause, related to Tkinter internal dependence on sub-layer of Tcl & Tk DLL services seems similar:
cit.:
"""
Using Tkinter, and bundle_files = 1, i get an immediate crash.
Here's my setup:
winxp sp2
py2exe 0.6.8
python 2.5.1
My test file is "example.py", as follows:
#### start
from Tkinter import *
if __name__ == '__main__':
print "hello"
#### end
my setup.py is as follows:
#### start
from distutils.core import setup
import py2exe
setup(
options = {'py2exe': {'bundle_files': 1}},
zipfile = None,
console=['example.py'])
#### end
it compiles just fine, but when running the "example.exe" that is produced in the "dist" directory, it immediately gets the error message "example.exe has encountered a problem and needs to close. We are sorry for the inconvenience".
Using the same setup.py, but with bundle_files = 3 works fine; using bundle_files = 2 causes the same crash.
I hope this is sufficient information to replicate this bug. I will be happy to provide any other info if you need it - just post back here.
"""
+ a there proposed workaround:
cit.:
"""
I "fixed" this by editing site-packages/py2exe/build_exe.py,
adding "tcl85.dll" and"tk85.dll" to the "dlls_in_exedir" list
-- meaning that they get put next to the .exe rather than bundled inside it.
Slightly messy, but much better than bundled=3

How to create a shortcut in startmenu using setuptools windows installer

I want to create a start menu or Desktop shortcut for my Python windows installer package. I am trying to follow https://docs.python.org/3.4/distutils/builtdist.html#the-postinstallation-script
Here is my script;
import sys
from os.path import dirname, join, expanduser
pyw_executable = sys.executable.replace('python.exe','pythonw.exe')
script_file = join(dirname(pyw_executable), 'Scripts', 'tklsystem-script.py')
w_dir = expanduser(join('~','lsf_files'))
print(sys.argv)
if sys.argv[1] == '-install':
print('Creating Shortcut')
create_shortcut(
target=pyw_executable,
description='A program to work with L-System Equations',
filename='L-System Tool',
arguments=script_file,
workdir=wdir
)
I also specified this script in scripts setup option, as indicated by aforementioned docs.
Here is the command I use to create my installer;
python setup.py bdist_wininst --install-script tklsystem-post-install.py
After I install my package using created windows installer, I can't find where my shorcut is created, nor I can confirm whether my script run or not?
How can I make setuptools generated windows installer to create desktop or start menu shortcuts?

Like others have commented here and elsewhere the support functions don't seem to work at all (at least not with setuptools). After a good day's worth of searching through various resources I found a way to create at least the Desktop shortcut. I'm sharing my solution (basically an amalgam of code I found here and here). I should add that my case is slightly different from yasar's, because it creates a shortcut to an installed package (i.e. an .exe file in Python's Scripts directory) instead of a script.
In short, I added a post_install function to my setup.py, and then used the Python extensions for Windows to create the shortcut. The location of the Desktop folder is read from the Windows registry (there are other methods for this, but they can be unreliable if the Desktop is at a non-standard location).
#!/usr/bin/env python
import os
import sys
import sysconfig
if sys.platform == 'win32':
from win32com.client import Dispatch
import winreg
def get_reg(name,path):
# Read variable from Windows Registry
# From https://stackoverflow.com/a/35286642
try:
registry_key = winreg.OpenKey(winreg.HKEY_CURRENT_USER, path, 0,
winreg.KEY_READ)
value, regtype = winreg.QueryValueEx(registry_key, name)
winreg.CloseKey(registry_key)
return value
except WindowsError:
return None
def post_install():
# Creates a Desktop shortcut to the installed software
# Package name
packageName = 'mypackage'
# Scripts directory (location of launcher script)
scriptsDir = sysconfig.get_path('scripts')
# Target of shortcut
target = os.path.join(scriptsDir, packageName + '.exe')
# Name of link file
linkName = packageName + '.lnk'
# Read location of Windows desktop folder from registry
regName = 'Desktop'
regPath = r'Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders'
desktopFolder = os.path.normpath(get_reg(regName,regPath))
# Path to location of link file
pathLink = os.path.join(desktopFolder, linkName)
shell = Dispatch('WScript.Shell')
shortcut = shell.CreateShortCut(pathLink)
shortcut.Targetpath = target
shortcut.WorkingDirectory = scriptsDir
shortcut.IconLocation = target
shortcut.save()
setup(name='mypackage',
...,
...)
if sys.argv[1] == 'install' and sys.platform == 'win32':
post_install()
Here's a link to a full setup script in which I used this:
https://github.com/KBNLresearch/iromlab/blob/master/setup.py

If you want to confirm whether the script is running or not, you can print to a file instead of the console. Looks like text you print to console in the post-install script won't show up.
Try this:
import sys
from os.path import expanduser, join
pyw_executable = join(sys.prefix, "pythonw.exe")
shortcut_filename = "L-System Toolsss.lnk"
working_dir = expanduser(join('~','lsf_files'))
script_path = join(sys.prefix, "Scripts", "tklsystem-script.py")
if sys.argv[1] == '-install':
# Log output to a file (for test)
f = open(r"C:\test.txt",'w')
print('Creating Shortcut', file=f)
# Get paths to the desktop and start menu
desktop_path = get_special_folder_path("CSIDL_COMMON_DESKTOPDIRECTORY")
startmenu_path = get_special_folder_path("CSIDL_COMMON_STARTMENU")
# Create shortcuts.
for path in [desktop_path, startmenu_path]:
create_shortcut(pyw_executable,
"A program to work with L-System Equations",
join(path, shortcut_filename),
script_path,
working_dir)

At least with Python 3.6.5, 32bit on Windows, setuptools does work for this. But based on the accepted answer, by trial and error I found some issues that may have caused your script to fail to do what you wanted.
create_shortcut does not accept keyword arguments, only positional, so its usage in your code is invalid
You must add a .lnk extension for Windows to recognise the shortcut
I found sys.executable will be the name of the installer executable, not the python executable
As mentioned, you can't see stdout or stderr so you might want to log to a text file. I would suggest also redirecting sys.stdout and sys.stderr to the log file.
(Maybe not relevant) as mentioned in this question there appears to be a bug with the version string generated by bdist_wininst. I used the hexediting hack from an answer there to work around this. The location in the answer is not the same, you have to find the -32 yourself.
Full example script:
import sys
import os
import datetime
global datadir
datadir = os.path.join(get_special_folder_path("CSIDL_APPDATA"), "mymodule")
def main(argv):
if "-install" in argv:
desktop = get_special_folder_path("CSIDL_DESKTOPDIRECTORY")
print("Desktop path: %s" % repr(desktop))
if not os.path.exists(datadir):
os.makedirs(datadir)
dir_created(datadir)
print("Created data directory: %s" % repr(datadir))
else:
print("Data directory already existed at %s" % repr(datadir))
shortcut = os.path.join(desktop, "MyModule.lnk")
if os.path.exists(shortcut):
print("Remove existing shortcut at %s" % repr(shortcut))
os.unlink(shortcut)
print("Creating shortcut at %s...\n" % shortcut)
create_shortcut(
r'C:\Python36\python.exe',
"MyModuleScript",
shortcut,
"",
datadir)
file_created(shortcut)
print("Successfull!")
elif "-remove" in sys.argv:
print("Removing...")
pass
if __name__ == "__main__":
logfile = r'C:\mymodule_install.log' # Fallback location
if os.path.exists(datadir):
logfile = os.path.join(datadir, "install.log")
elif os.environ.get("TEMP") and os.path.exists(os.environ.get("TEMP"),""):
logfile = os.path.join(os.environ.get("TEMP"), "mymodule_install.log")
with open(logfile, 'a+') as f:
f.write("Opened\r\n")
f.write("Ran %s %s at %s" % (sys.executable, " ".join(sys.argv), datetime.datetime.now().isoformat()))
sys.stdout = f
sys.stderr = f
try:
main(sys.argv)
except Exception as e:
raise
f.close()
sys.exit(0)

UPD: on an off chance that the client machine has pywin32 installed, we try in-process creation first. Somewhat cleaner that way.
Here is another take. This assumes the package is called myapp, and that also becomes the executable that you want a shortcut to. Substitute your own package name and your own shortcut text.
Uses a Windows Scripting Host COM class - in process if possible, inside a Powershell command line as a subprocess if not. Tested on Python 3.6+.

Python py2exe window showing (tkinter)

I'm trying to make an exe by py2exe. The program is showing a popup-like window using Tkinter. The problem is, everything works fine when I run the setup like this:
setup(windows = [{'script': "msg.py"}], zipfile = None)
but it fails when I try to make an one-file exe:
setup(windows = [{'script': "msg.py"}], zipfile = None, options = {'py2exe': {'bundle_files': 1, 'compressed': True}})
Actually the final exe runs without problems, but it doesn't display any window. I've read there may be problems with bundle_files=1 at Windows 7, but I also tried bundle_files=2 with the same effect.
Here is my msg.py script:
from win32gui import FindWindow, SetForegroundWindow
from Image import open as iopen
from ImageTk import PhotoImage
from Tkinter import Tk, Label
from threading import Timer
from subprocess import Popen
import os
def Thread(t, fun, arg=None):
if arg<>None: x = Timer(t, fun, arg)
else: x = Timer(t, fun)
x.daemon = True
x.start()
def NewMessage():
global root
if not os.path.exists('dane/MSG'):
open('dane/MSG', 'w').write('')
root = Tk()
img = PhotoImage(iopen("incl/nowa.png"))
label = Label(root, image=img)
label.image = img
label.bind("<Button-1>", Click)
label.pack()
root.geometry('-0-40')
root.wm_attributes("-topmost", 1)
root.overrideredirect(1)
root.mainloop()
def Click(event):
global root, exit
root.destroy()
os.remove('dane/MSG')
OpenApp()
exit = True
def OpenApp():
hwnd = FindWindow(None, 'My program name')
if hwnd: SetForegroundWindow(hwnd)
else: Popen('app.exe')
root, exit = None, False
NewMessage()
Any ideas? I've read there are some problems with Tkinter, but there were about compilation. My script is compiled and it doesn't throw any exceptions, but doesn't show the window...

I ended up encountering this same issue, my solution involved doing the following:
Add
"dll_excludes": ["tcl85.dll", "tk85.dll"],
in your options = {...}
and then manually copy those two DLLs from
PYTHON_PATH\DLLs\ (in my case C:\Python27\DLLs)
to the location of your exe and try running it.

An alternative to dll_excludes and manual copying is to patch py2exe to know these files have to be placed directly in the dist directory.
Inside build_exe.py, there's a class called py2exe, which contains a list dlls_in_exedir for dll that have to go there. This list is set during a function named plat_prepare, and you can add the tclXX.dll and tkXX.dll files to it to make sure they are copied correctly.
Of course, unless you're the only one who will ever build this, you don't necessarily know which Tcl and Tk version you need to bundle - someone might have built their Python themselves, or are using an older Python with older DLLs. Therefore, you'll need to check which versions the system is actually using. py2exe actually already does this in a different place: by importing the internal _tkinter module (the actual Tk interface, usually a DLL) and accessing TK_VERSION and TCL_VERSION, which you can then use to generate and add the correct filenames.
If others are supposed to build your application, you probably don't want to make them modify their py2exe install, so here's how you can monkeypatch it from your setup.py:
import py2exe
py2exe.build_exe.py2exe.old_prepare = py2exe.build_exe.py2exe.plat_prepare
def new_prep(self):
self.old_prepare()
from _tkinter import TK_VERSION, TCL_VERSION
self.dlls_in_exedir.append('tcl{0}.dll'.format(TCL_VERSION.replace('.','')))
self.dlls_in_exedir.append('tk{0}.dll'.format(TK_VERSION.replace('.','')))
py2exe.build_exe.py2exe.plat_prepare = new_prep
This even works with bundle_files=1 on Windows 7.

If you have only one version the you can copy files with
via data_file. Below a full example:

How can I change my desktop background with python?

How can I change my desktop background with python?
I want to do it in both Windows and Linux.

On Windows with python2.5 or higher, use ctypes to load user32.dll and call SystemParametersInfo() with SPI_SETDESKWALLPAPER action.
For example:
import ctypes
SPI_SETDESKWALLPAPER = 20
ctypes.windll.user32.SystemParametersInfoA(SPI_SETDESKWALLPAPER, 0, "image.jpg" , 0)

For Python3.5, SystemParametersInfoA doesn't work. Use SystemParametersInfoW.
import ctypes
ctypes.windll.user32.SystemParametersInfoW(20, 0, "absolute path" , 0)

I use the following method in one of my initial projects:

The get_desktop_environment method has been posted in another thread.

On a gnome desktop, you usually do this with gconf, either directly calling gconftool or using the gconf python module. The latter is in the link given by unutbu. The first method could be done like this.
import commands
command = "gconftool-2 --set /desktop/gnome/background/picture_filename --type string '/path/to/file.jpg'"
status, output = commands.getstatusoutput(command) # status=0 if success

In gnome, it is probably preferable to use the python binding of gconf directly:
import gconf
conf = gconf.client_get_default()
conf.set_string('/desktop/gnome/background/picture_filename','/path/to/filename.jpg')

On windows, you will need some trickery with pywin32, and the windows API, on 'linux' the answer will depend on which desktop is running - KDE, Gnome, or something more exotic. Under KDE (and maybe Gnome) you can probably send a message using D-Bus, which you could do without including any new libraries by using the command line tool dbus-send.
The other option would be to set the desktop wallpaper to a file which you then edit / replace from python - but this will probably only result in a change when the user logs in.

Firstly, import ctypes: it gives you access to windows components such as the screensaver, wallpapers, etc.
Then call
ctypes.windll.user32.SystemParametersInfoA(20, 0, the_complete_path_of_your_image, 0)
Make sure the path is the complete path of your image, not just the path from the active directory

There is a difference what SystemParametersInfo method to be called based on what if you are running on 64 bit or 32 bit OS. For 64 bit you have to use SystemParametersInfoW (Unicode) and for 32 bit SystemParametersInfoA (ANSI)
import struct
import ctypes
SPI_SETDESKWALLPAPER = 20
WALLPAPER_PATH = 'C:\\your_file_name.jpg'
def is_64_windows():
"""Find out how many bits is OS. """
return struct.calcsize('P') * 8 == 64
def get_sys_parameters_info():
"""Based on if this is 32bit or 64bit returns correct version of SystemParametersInfo function. """
return ctypes.windll.user32.SystemParametersInfoW if is_64_windows() \
else ctypes.windll.user32.SystemParametersInfoA
def change_wallpaper():
sys_parameters_info = get_sys_parameters_info()
r = sys_parameters_info(SPI_SETDESKWALLPAPER, 0, WALLPAPER_PATH, 3)
# When the SPI_SETDESKWALLPAPER flag is used,
# SystemParametersInfo returns TRUE
# unless there is an error (like when the specified file doesn't exist).
if not r:
print(ctypes.WinError())
change_wallpaper()

import ctypes,win32con
def getWallpaper():
ubuf = ctypes.create_unicode_buffer(512)
ctypes.windll.user32.SystemParametersInfoW(win32con.SPI_GETDESKWALLPAPER,len(ubuf),ubuf,0)
return ubuf.value
def setWallpaper(path):
changed = win32con.SPIF_UPDATEINIFILE | win32con.SPIF_SENDCHANGE
ctypes.windll.user32.SystemParametersInfoW(win32con.SPI_SETDESKWALLPAPER,0,path,changed)
Alternatively: (with SystemParametersInfoA)
def getWallpaper():
sbuf = ctypes.create_string_buffer(512) # ctypes.c_buffer(512)
ctypes.windll.user32.SystemParametersInfoA(win32con.SPI_GETDESKWALLPAPER,len(sbuf),sbuf,0)
return sbuf.value
def setWallpaper(path):
changed = win32con.SPIF_UPDATEINIFILE | win32con.SPIF_SENDCHANGE
ctypes.windll.user32.SystemParametersInfoA(win32con.SPI_SETDESKWALLPAPER,0,path.encode(),changed) # "".encode() = b""
Arguments are:
SystemParametersInfo(SetOrGet, GetBufferSize, SetBufferOrGetBuffer, SetChange)
The path has to be absolute, so if you're using something relative to your script, do:
path = os.path.abspath(path)
To see more stuff you can do with SystemParametersInfo, see the docs.
(near the bottom there's an example to change the mouse speed)
P.S. There are many answers already here, but they're leaving out the broadcasting you're supposed to do. Sure it works without it, but it's bad practice not to use it properly.
P.P.S And they only gave hard coded values, rather than the variables they come from.
Also note, i use 512 characters for the buffer size when getting the path, just to be more safe since paths might exceed 256. I doubt anyone will have paths as long as that though.
One more note. I've only tested the above examples in Python 3, but i don't think SystemParametersInfoA needs the .encode() in Python 2. (they updated strings in Python 3 to unicode i believe) The string in SystemParametersInfoW may need converting for Python 2.

I read all the answers and after searching for a while i found a easier solution.
Install the module named py-wallpaper.
pip install py-wallpaper
Import the module.
from wallpaper import set_wallpaper, get_wallpaper
set the wallpaper using set walpaper
set_wallpaper("location/to/image.jpg")
get the current wallpaper's path using get wallpaper
print(get_wallpaper())
thanks.

changing the background image of desktop
import ctypes
import os
SPI_SETDESKWALLPAPER = 20
ctypes.windll.user32.SystemParametersInfoA(SPI_SETDESKWALLPAPER, 0, 'your image path', 3)
#'C:\\Users\\Public\\Pictures\\abc.jpg'
it worked fine for me. windows10, python27

On Windows with python2.5 or higher, use ctypes to load user32.dll and call
import ctypes
ctypes.windll.user32.SystemParametersInfoW(20,0,"Path_wallpaper", 0)
speak("Background changed succesfully")

Just adding a small precision to ShivaGuntuku 's post :
In python 3 you should replace the 'A' by a 'W' in SytemParametersInfoA. Small exemple to change your desktop background in windows10 with python 3 :
import ctypes
import os
SPI_SETDESKWALLPAPER = 20
ctypes.windll.user32.SystemParametersInfoW(
SPI_SETDESKWALLPAPER, 0, 'C:\\Users\\godet\\OneDrive\\Images\\breaker_wall.jpg', 0)

this works for me
import ctypes
ctypes.windll.user32.SystemParametersInfoW(20,0,path:os.PathLike,3)

You can use this library PyWallpaper, worked for me on mac also.
To install type pip install PyWallpaper.
And then to change/set your wallpaper -
from PyWallpaper import change_wallpaper
change_wallpaper("/some_path/sample.jpg")

How can I find the full path to a font from its display name on a Mac?

I am using the Photoshop's javascript API to find the fonts in a given PSD.
Given a font name returned by the API, I want to find the actual physical font file that font name corresponds to on the disc.
This is all happening in a python program running on OSX so I guess I'm looking for one of:
Some Photoshop javascript
A Python function
An OSX API that I can call from python

Unfortunately the only API that isn't deprecated is located in the ApplicationServices framework, which doesn't have a bridge support file, and thus isn't available in the bridge. If you're wanting to use ctypes, you can use ATSFontGetFileReference after looking up the ATSFontRef.
Cocoa doesn't have any native support, at least as of 10.5, for getting the location of a font.

open up a terminal (Applications->Utilities->Terminal) and type this in:
locate InsertFontHere
This will spit out every file that has the name you want.
Warning: there may be alot to wade through.

I haven't been able to find anything that does this directly. I think you'll have to iterate through the various font folders on the system: /System/Library/Fonts, /Library/Fonts, and there can probably be a user-level directory as well ~/Library/Fonts.

There must be a method in Cocoa to get a list of fonts, then you would have to use the PyObjC bindings to call it..
Depending on what you need them for, you could probably just use something like the following..
import os
def get_font_list():
fonts = []
for font_path in ["/Library/Fonts", os.path.expanduser("~/Library/Fonts")]:
if os.path.isdir(font_path):
fonts.extend(
[os.path.join(font_path, cur_font)
for cur_font in os.listdir(font_path)
]
)
return fonts

I had encountered similar requirements and I ended up by this method:
def get_font_path(font):
ttf_filename = os.path.basename(font)
dirs = []
if sys.platform == "win32":
# check the windows font repository
# NOTE: must use uppercase WINDIR, to work around bugs in
# 1.5.2's os.environ.get()
windir = os.environ.get("WINDIR")
if windir:
dirs.append(os.path.join(windir, "fonts"))
elif sys.platform in ("linux", "linux2"):
lindirs = os.environ.get("XDG_DATA_DIRS", "")
if not lindirs:
# According to the freedesktop spec, XDG_DATA_DIRS should
# default to /usr/share
lindirs = "/usr/share"
dirs += [
os.path.join(lindir, "fonts") for lindir in lindirs.split(":")
]
elif sys.platform == "darwin":
dirs += [
"/Library/Fonts",
"/System/Library/Fonts",
os.path.expanduser("~/Library/Fonts"),
]
ext = os.path.splitext(ttf_filename)[1]
first_font_with_a_different_extension = None
for directory in dirs:
for walkroot, walkdir, walkfilenames in os.walk(directory):
for walkfilename in walkfilenames:
if ext and walkfilename == ttf_filename:
return os.path.join(walkroot, walkfilename)
elif (
not ext
and os.path.splitext(walkfilename)[0] == ttf_filename
):
fontpath = os.path.join(walkroot, walkfilename)
if os.path.splitext(fontpath)[1] == ".ttf":
return fontpath
if (
not ext
and first_font_with_a_different_extension is None
):
first_font_with_a_different_extension = fontpath
if first_font_with_a_different_extension:
return first_font_with_a_different_extension
Note that the original code is from PIL

With matplotlib (pip3 install -U matplotlib):
from matplotlib import font_manager
fontmap = {font.name: font for font in font_manager.fontManager.ttflist}
fontmap.update({font.name: font for font in font_manager.fontManager.afmlist})
print(f'Total fonts: {len(fontmap.keys())}')
for family in sorted(fontmap.keys()):
font = fontmap[family]
print(f'{family:<30}: {font.fname}')
Sample output
Total fonts: 312

NOTE: The font families from matplotlib do not seem to include all system fonts that are available for example to the PyQt5 library:
from PyQt5.QtGui import QFontDatabase
from PyQt5.QtWidgets import QApplication
app = QApplication([])
print('\n'.join(QFontDatabase().families()))
