Is there any way to user autocomplete in embarcadero PyScripter or PyChamr?
I really want to write python scripts using the delphivlc library, but it's real hard when I can't use autocomplete.
And...
Do you people know why GUI interface stop responding when moving files using python?
I have 3 game libraries installed on my PC: pyglet, pygame and Panda3D.
I would like to create a 2D game and make it a web browser game so i can put it on facebook.
I know that Panda3D has a web-browser-plugin. Panda3D is for 3D games mainly.
Therefore, I'm asking, is it possible to play a pyglet or pygame game in a browser? If not, what Python library do you recommend?
Neither pyglet nor pygame will run in a browser. I wouldn't really recommend using Python at all if you target is a web browser. JavaScript (with HTML5 Canvas), Flash, or Java applets are is better suited for that environment.
If you're dedicated to the idea of using Python, there are a number of projects that can compile Python into JavaScript. There are some mentioned on the Python wiki. Here are a few:
Skulpt
Pyjamas
Pyjaco
You'll need to write your own graphics and audio systems, though, since none of those projects can convert the native code needed by pyglet and pygame into JavaScript.
It requires a bit of reprogramming, but i made a pygame library "port" to the browser/nodewebkit using Brython and GameJS. You can program using a version of pygame and python 3 in the browser. You can check it out at https://github.com/asherwunk/pygjs
An option is to use repl.it. It allows creating Python/PyGame scripts and multiplayer coding. When creating a new repl, select the Pygame template:
Example: repl.it/#Rabbid76/PyGame-TransparentShapes
Today, i'd recommand using pygbag https://pypi.org/project/pygbag/ from https://pygame-web.github.io. It uses the same principles from Panda3D webgl port ( not the old plugin) using Web Assembly for modern browsers.
I just found this website https://trinket.io/features/pygame that allows you to run pygame from this website! But it's extremely slow. It should work from your browser but it'll take forever to run it.
CLI applications like Vim, cdargs can open a new screen then allow users to draw characters there. I'd like to try making some tools like that with Node and was told that it was called "alternative screen"(?).
I'm familiar with JS. But if there's not a solution, Python maybe(..) OK. Want some code example please :)
Found a modules according to tMC's anwser, trying to figure out...
https://github.com/mscdex/node-ncurses
Vim uses the ncurses library to do drawing. You have already found a Node.JS bindings, so you should have no trouble using this library within your application.
I propose you to read the NCURSES tutorial and attempt to do it in Node.JS.
We have console application option in C#, but how do I can make a console GUI in python?
I should note I want to compile and use my program in windows.
Also I want to select Items in Python GUI by Enter button.
If you're using Windows you will ultimately need to integrate with the win32 console API to create a console GUI (aka. a Text UI or TUI). Your options are basically:
Write your TUI using curses or the packages that sit on top of it, like urwid or npyscreen. To do this you either need to install cygwin or PDcurses to make it work.
Write to the win32 API directly using something like pywin32.
Use a package that simplifies the win32 API like effbot's console package.
I found all the above unsatisfactory as I didn't want all the hassle of installing 3rd party binaries for Windows and wanted an API that I could use anywhere (after a simple pip install), so I wrote a cross-platform package (asciimatics) to fix it. This package takes all the hassle away and provides a clean, documented API with a set of widgets for TUI applications.
For example the following is a screenshot of the contacts list sample code referenced in the previous docs link, showing some of the basic text and button widgets.
Take a look at Python's curses library:
http://docs.python.org/howto/curses.html
http://www.dev-explorer.com/articles/python-with-curses
http://docs.python.org/library/curses.html
If you'd like a Python shell, then you might want to look at something like PyFlakes / PyShell or similar.
Python works on multiple platforms and can be used for desktop and web applications, thus I conclude that there is some way to compile it into an executable for Mac, Windows and Linux.
The problem being I have no idea where to start or how to write a GUI with it, can anybody shed some light on this and point me in the right direction please?
First you will need some GUI library with Python bindings and then (if you want) some program that will convert your python scripts into standalone executables.
Cross-platform GUI libraries with Python bindings (Windows, Linux, Mac)
Of course, there are many, but the most popular that I've seen in wild are:
Tkinter - based on Tk GUI toolkit (de-facto standard GUI library for python, free for commercial projects)
WxPython - based on WxWidgets (popular, free for commercial projects)
Qt using the PyQt bindings or Qt for Python. The former is not free for commercial projects. The latter is less mature, but can be used for free.
Complete list is at http://wiki.python.org/moin/GuiProgramming
Single executable (all platforms)
PyInstaller - the most active(Could also be used with PyQt)
fbs - if you chose Qt above
Single executable (Windows)
py2exe - used to be the most popular
Single executable (Linux)
Freeze - works the same way like py2exe but targets Linux platform
Single executable (Mac)
py2app - again, works like py2exe but targets Mac OS
Another system (not mentioned in the accepted answer yet) is PyInstaller, which worked for a PyQt project of mine when py2exe would not. I found it easier to use.
http://www.pyinstaller.org/
Pyinstaller is based on Gordon McMillan's Python Installer. Which is no longer available.
An alternative tool to py2exe is bbfreeze which generates executables for windows and linux. It's newer than py2exe and handles eggs quite well. I've found it magically works better without configuration for a wide variety of applications.
There's also PyGTK, which is basically a Python wrapper for the Gnome Toolkit. I've found it easier to wrap my mind around than Tkinter, coming from pretty much no knowledge of GUI programming previously. It works pretty well and has some good tutorials. Unfortunately there isn't an installer for Python 2.6 for Windows yet, and may not be for a while.
Since python is installed on nearly every non-Windows OS by default now, the only thing you really need to make sure of is that all of the non-standard libraries you use are installed.
Having said that, it is possible to build executables that include the python interpreter, and any libraries you use. This is likely to create a large executable, however.
MacOS X even includes support in the Xcode IDE for creating full standalone GUI apps. These can be run by any user running OS X.
For the GUI itself:
PyQT is pretty much the reference.
Another way to develop a rapid user interface is to write a web app,
have it run locally and display the app in the browser.
Plus, if you go for the Tkinter option suggested by lubos hasko
you may want to try portablepy to have your app run on Windows environment
without Python.
I'm not sure that this is the best way to do it, but when I'm deploying Ruby GUI apps (not Python, but has the same "problem" as far as .exe's are concerned) on Windows, I just write a short launcher in C# that calls on my main script. It compiles to an executable, and I then have an application executable.
PySimpleGUI wraps tkinter and works on Python 3 and 2.7. It also runs on Qt, WxPython and in a web browser, using the same source code for all platforms.
You can make custom GUIs that utilize all of the same widgets that you find in tkinter (sliders, checkboxes, radio buttons, ...). The code tends to be very compact and readable.
#!/usr/bin/env python
import sys
if sys.version_info[0] >= 3:
import PySimpleGUI as sg
else:
import PySimpleGUI27 as sg
layout = [[ sg.Text('My Window') ],
[ sg.Button('OK')]]
window = sg.Window('My window').Layout(layout)
button, value = window.Read()
As explained in the PySimpleGUI Documentation, to build the .EXE file you run:
pyinstaller -wF MyGUIProgram.py
!!! KIVY !!!
I was amazed seeing that no one mentioned Kivy!!!
I have once done a project using Tkinter, although they do advocate that it has improved a lot, it still gives me a feel of windows 98, so I switched to Kivy.
I have been following a tutorial series if it helps...
Just to give an idea of how kivy looks, see this (The project I am working on):
And I have been working on it for barely a week now !
The benefits for Kivy you ask? Check this
The reason why I chose this is, its look and that it can be used in mobile as well.
# I'd use tkinter for python 3
import tkinter
tk = tkinter.Tk()
tk.geometry("400x300+500+300")
l = Label(tk,text="")
l.pack()
e = Entry(tk)
e.pack()
def click():
e['text'] = 'You clicked the button'
b = Button(tk,text="Click me",command=click)
b.pack()
tk.mainloop()
# After this I would you py2exe
# search for the use of this module on stakoverflow
# otherwise I could edit this to let you know how to do it
py2exe
Then you should use py2exe, for example, to bring in one folder all the files needed to run the app, even if the user has not python on his pc (I am talking of windows... for the apple os there is no need of an executable file, I think, as it come with python in it without any need of installing it.
Create this file
Create a setup.py
with this code:
from distutils.core import setup
import py2exe
setup(console=['l4h.py'])
save it in a folder
Put your program in the same folder of setup.py
put in this folder the program you want to make it distribuitable:
es: l4h.py
ps: change the name of the file (from l4h to anything you want, that is an example)
Run cmd from that folder (on the folder, right click + shift and choose start cmd here)
write in cmd:>python setup.py py2exe
in the dist folder there are all the files you need
you can zip it and distribute it
Pyinstaller
Install it from cmd
**
pip install pyinstaller
**
Run it from the cmd from the folder where the file is
**
pyinstaller file.py
**
Update
Read this post to make an exe on windows with pyinstaller the proper way and with one file and images in it https://pythonprogramming.altervista.org/auto-py-to-exe-only-one-file-with-images-for-our-python-apps/
You don't need to compile python for Mac/Windows/Linux. It is an interpreted language, so you simply need to have the Python interpreter installed on the system of your choice (it is available for all three platforms).
As for a GUI library that works cross platform, Python's Tk/Tcl widget library works very well, and I believe is sufficiently cross platform.
Tkinter is the python interface to Tk/Tcl
From the python project webpage:
Tkinter is not the only GuiProgramming
toolkit for Python. It is however the
most commonly used one, and almost the
only one that is portable between
Unix, Mac and Windows
You can use appJar for basic GUI development.
from appJar import gui
num=1
def myfcn(btnName):
global num
num +=1
win.setLabel("mylabel", num)
win = gui('Test')
win.addButtons(["Set"], [myfcn])
win.addLabel("mylabel", "Press the Button")
win.go()
See documentation at appJar site.
Installation is made with pip install appjar from command line.
There's three things you could do:
The first thing is to find a GUI Designer that can launch its code as standalone applications like .exe files. I use a version of MatDeck (for people using GUI Designers I recommend MD Python Designer) as I believe(I use another version so I'm not too sure.) it allows me to convert the code to a standalone applications and by having it as such, there is no need to install the software on every PC that's going to run the program.
The second option is partially bypassing the problem, launch the GUI as a web page. This would give you the most compatibility as most if not all OS can utilize it. Once again, you would need a GUI Designer that can convert its components into a web compatible format, I've done it once and I used the same version of MatDeck(Visionary Deck), I would not recommend MD Python Designer this time as I don't know if it can turn its GUIs into websites using web assembly whereas Visionary Deck I've tried and tested. As with all things there are most likely other software this is just one I use frequently because I work a lot with Mathematics and Physics.
The third option is also kind of bypassing the problem but do it in Tkinter and just ensure you have a Python IDE or just plain old Python and run the code, this will launch the GUI. This is a good solution and maybe the simplest but I wouldn't class it as the shortest or the best. If you only plan to switch between a few operating systems and computers this will probably be your best bet.
