I have a quick question about the default working directly on python.
I am currently using the python 2.7. In this case the default working directly is the C:/Python27.
I want to change this permanently to another directory.
Even if we write down following on shell, the default working directory will go back to the original C:/Python27 automatically.
import os
os.chdir('a path')
Does any one know how to set up default directory permanently to "the path" which keeps the directory after the closing the shell?
This is a different question from how to change working directory just by the function temporarily.
Thank you so much for your help!!
The working directory of the python directory is the directory from which it was started. If from a console (cmd.exe) I do cd /some/dir and then start python, its working directory will be /some/dir.
If you want an interactive console started at a given directory you have some options:
Using a shortcut, you can change its Start in field, in the properties tab, to point to your target directory.
Use IPython instead, and add a startup script to the default profile so it always start at the target directory. IPython is an enhanced interactive with lots of useful features.
If you are running from a script and want to switch to the folder where you script is stored, you could use os.cd(os.path.dirname(__file__)).
If you are launching Python from the start menu of Windows, right click on the icon and select more -> file location.
Once there you can right click on the shortcut and select properties. From there you should be able to define the 'Start in:' location.

Ok, so I'm looking to switch to PyCharm from PyScripter for OS independent development. I also wanted to mention that I'm using Perforce for version control.
So what I currently do is double click a .py for editing in Perforce, and PyScripter opens up and I edit to my hearts desire. I can click on an imported function, and it'll open up the corresponding .py file and bring me right to the function. Awesome.
So I have yet to be able to achieve that on PyCharm. I'm using the community version which should be just fine for what I want, which is just an editor with some python checking & built in console.
When I set the default .py program to use in Perforce to PyCharm, I click on the .py and PyCharm fires up. Good so far. But my problem arises when I try to "ctrl + click" a function or method. I get the "Cannot find declaration to go to." I import the associated class & file.
(Just an example, not actual code). So in Transportation.py I have "import Cars", which is a .py. I do Cars.NumberOfDoors() and I get the above error. My folder structure is:
Scripts (folder)
Population.py (General support script)
Citybudget.py (General support script)
MassTransit (folder)
Transportation.py
Cars.py
So question boils down to, is how do I properly setup the root to be the Scripts folder when I click on a file from Perforce? How do I set it up that it recognizes where it's at in the folder structure? So if I'm in the MassTransit it'll set the root as Scripts folder, and same for if I'm accessing the general support scripts like Population.py?
Go to
File --> Open
in Pycharm and select your Scripts(folder) and open it. Then the Pycharm will treat it as a project and you will be able to ctrl + click a function.
I am developing a key-logger on Python (only for curiosity sake). And the script will be an executable. The process will not need a UI or user interaction.
Is there any way, even in another executable to make the key-logger start at start-up?
I don't use Windows, but you can try making a batch script that runs your python file and make that script Run a program automatically when Windows starts:
Click the Start button Picture of the Start button , click All
Programs, right-click the Startup folder, and then click Open.
Open the location that contains the item you want to create a shortcut
to.
Right-click the item, and then click Create Shortcut. The new
shortcut appears in the same location as the original item.
Drag the shortcut into the Startup folder.
As I said, I don't use Windows, so it might be totally wrong.
You can refer here for making the BAT file, which basically says:
#echo off
python c:\somescript.py %*
pause
I think that the above answers are too complex. What I did was just drag and drop or copy and paste my file in the startup folder by clicking the quick access toolbar, typing "startup", and the job is done.
I am using Windows 10 operating system, so it might be different in your case.
I hope this is useful.
Edit: The key to this solution is to have the .py extension files open by default by the python console (not a text editor), otherwise it will just open the file instead of executing it. In order to select the default program a type of file is opened with, right click on the .py file -> Open with -> Choose default program. See this example:
Use VBScript:
1-> create anyname.vbs with this data:
Set wvbs=CreateObject("Wscript.Shell")
wvbs.run "full location of your File",0
2-> copy anyname.vbs file in C:\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup this folder
Now when windows start it will run your file in hidden mode
Open run with "Start + R", then open "shell:startup". it opens you a folder(the folder that was mentioned before at start menu), and every file that is on this folder, well run at startup.
The folder path is: "C:\Users\USERNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup" (you can copy it on windows explorer, or copy this path and put your account name on USERNAME)
this is the trick i used in my script:
from os import getcwd
from shutil import copy
copy(getcwd()+'/FILE_NAME.exe','C:/Users/USERNAME/AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Startup')
They are some ways for file name as well, but im not familiar with it. this code copies it self to startup folder and starts each time windows boots
Create a shortcut in the shell:startup folder with an absolute path to your pythonw.exe executable. The w version of Python is needed so that it starts up without a shell in the background.
Detailed instructions
Open the startup folder
Type the Windows and R keys at the same time. In the Run dialog, type shell:startup and it enter. This takes you to the Startup folder. Shorcuts in this folder are launched when the computer starts. (For me, the startup folder is at C:\Users\username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup.)
Create new shortcut
Right-click in this folder and say "New shortcut." Browse to "This PC," "Windows (C:)," "Program Files,", "Python39", and select pythonw.exe. Your Python install is likely in a different location. More recently, Python is found somewhere within %appdata%. (You can paste %appdata% into the run dialog to open this folder and look for Python. It opens in Roaming by default, but be sure to look in Local, too.)
As mentioned at the start of this answer, it is important that you select pythonw.exe rather than python.exe as pythonw.exe will run without opening a command prompt.
On the next "Create Shortcut" screen, titled, "What would you like to name the shortcut," you can name it whatever you want. For the OP, I recommend "Self penetration test."
Click "Finish."
Edit the shortcut to launch your script
In the Startup folder, right click on the app you just created and select "Properties."
In the Properties dialog's Shortcut tab, edit the "Target" to look something like "C:\Program Files\Python310\pythonw.exe" pentest_keylogger.py and the "Start in" to be the folder in which pentest_keylogger.py is found. (As above, you will need to use your Python distribution's path.)
Test your script
Hit OK. Then double-click on the icon to see if it works silently as you desire.
Finally, reboot your machine and use resmon (from the run dialog) or Ctl-Alt-Delete and the task manager to see if your app is running in the background.

The installation directory is "d:\python2.7", and every time I open IDLE and click on menu File and Open item, the default directory is also "d:\python2.7". So I have to change the directory to where I want.
Is there any way I can change it? Using configuration file or changing environment variable?
I tried to add PYTHONPATH in environment variable, but it doesn't work.
I also import os, and use os.chdir(), but it only changes the working directory, not what I want.
Thank you.
If you're running IDLE from a Windows shortcut, you can just right-click on the shortcut, choose "Properties", and change the field "Start in" to any directory you like.
In response to the answer by Aya:
If you're running IDLE from a Windows shortcut, you can just right-click on the shortcut, choose "Properties", and change the field "Start in" to any directory you like.
Yes you can, however Python IDLE will no longer run. I've found that if the Start In directory for the IDLE shortcut is C:\Python33 or C:\Python33\Lib\idlelib (in my case) that it will still work but if I added a new directory below either of these (for example: myfiles) containing my programs then the IDLE editor fails. In my situation, I've spend days now trying to get Python to easily get to my .py programs by clicking FILE+OPEN in the IDLE editor. Also, I've tried everything to get IDLE to run without failing from the Windows Explorer using right click and selecting "edit with IDLE" but although Idle does opens okay trying to RUN a program from there fails. I did manage to get IDLE to work using SEND TO and until I get an answer to my IDLE issue Post that is what I suppose I will have to do. Hope this helps.
Open the idle or PyShell
press Alt + M or File -> open Module
type in idlelib.IOBinding
the window opens, go to line 185
change either 'dirname = None' or 'filename = None' to the value you desire.
Eventually you need to start the PyShell or the editor with rights to edit this module like
sudo idle
if you can not edit it you need to see idle.pyw in the same directory an trace how IOBinding is used by the idlelib.PyShell.main() function and change the same variable.
How does one acquire the directory of the Windows Shortcut calling a python script. I'd like to have multiple shortcuts in various places pointing to one script that I could edit if I wanted, but where the directory from which the script is called is accessible. Is this possible?
This script would likely then be compiled with py2exe or something, so if it is something that isn't possibly until THAT stage, I could go with that. Thanks!
The easiest solution is to just use a batch script instead of a shortcut.
All it needs is python C:\path\to\script\script.py, and the script will have the correct CWD.
The default when creating a shortcut on windows is for the Start in: property to be set to the folder the linked file resides in.
The script has no knowledge of the fact that it was called from a shortcut, let alone where that shortcut resides.
You can change the Start in: property of the shortcut to the path of the folder the shortcut resides in.
Then you can use os.getcwd() to get that path.
Unfortunately setting Start in: to . doesn't work.
In general you cannot obtain this information. You should use argv to switch behaviour of your script.
you can do so with
import os
print os.getcwd()
os.getcwd()
Return a string representing the current working directory.
Availability: Unix, Windows.
Does anyone know where or how to set the default path/directory on saving python scripts prior to running?
On a Mac it wants to save them in the top level ~/Documents directory. I would like to specify a real location. Any ideas?
On OS X, if you launch IDLE.app (by double-clicking or using open(1), for example), the default directory is hardwired to ~/Documents. If you want to change the default permanently, you'll need to edit the file idlemain.py within the IDLE.app application bundle; depending on which Python(s) you have installed, it will likely be in one of:
/Applications/MacPython 2.x/IDLE.app/Contents/Resources
/Applications/MacPython 2.x/IDLE.app/Contents/Resources
/Applications/MacPorts/Python 2.x/IDLE.app/Contents/Resources
/Applications/Python 2.x/IDLE.app/Contents/Resources
/Applications/Python 3.x/IDLE.app/Contents/Resources
Edit the line:
os.chdir(os.path.expanduser('~/Documents'))
On the other hand, if you start IDLE from the command line, for example, with:
$ cd /some/directory
$ /usr/local/bin/idle
IDLE will use that current directory as the default.
I actually just discovered the easiest answer, if you use the shortcut link labeled "IDLE (Python GUI)". This is in Windows Vista, so I don't know if it'll work in other OS's.
1) Right-click "Properties".
2) Select "Shortcut" tab.
3) In "Start In", write file path (e.g. "C:\Users...").
Let me know if this works!
In Windows 10+, click the Windows Start button, then type idle, and then right-click on the IDLE desktop app and open the file location. This should bring you to the Start Menu shortcuts for Python, and you'll find a shortcut to IDLE there. Right-click on the IDLE shortcut and select properties. Set the "Start in" directory to be where you want default save path to be.
It seems like you can get idle into the directory you want if you run any module from that directory.
I had previously tried opening idlemain.py through the path browser. I was able to open and edit the file, but it seemed like I wasn't able to save my modifications.
I'm just glad to hear other people are having this problem. I just thought I was being stupid.
If you open a module, that sets the default working directory.
Start IDLE.
File -> Open to open your file. And set the current working directory.
In my case, the default directory is set to the directory from which I launched IDLE. For instance, if I launched IDLE from a directory called 'tmp' in my home directory, the default save path is set to ~/tmp. So start your IDLE like this:
~/tmp $ idle
[...]
On Windows (Vista at least, which is what I'm looking at here), shortcut icons on the desktop have a "Start in" field where you can set the directory used as the current working directory when the program starts. Changing that works for me. Anything like that on the Mac? (Starting in the desired directory from the command line works, too.)
For OS X:
Open a new finder window,then head over to applications.
Locate your Python application. (For my mac,it's Python 3.5)
Double click on it.
Right click on the IDLE icon,show package contents.
Then go into the contents folder,then resources.
Now,this is the important part:
(Note: You must be the administrator or have the administrator's password for the below to work)
Right click on the idlemain.py,Get Info.
Scroll all the way down. Make sure under the Sharing & Permissions tab,your "name"(Me) is on it with the privilege as Read & Write.
If not click on the lock symbol and unlock it.
Then add/edit yourself to have the Read & Write privilege.
Lastly,as per Ned Deily's instructions,edit the line:
os.chdir(os.path.expanduser('~/Documents'))
with your desired path and then save the changes.
Upon restarting the Python IDLE,you should find that your default Save as path to be the path you've indicated.
I am using windows 7 and by going to Start-> IDLE(Python 3.6 32-bit)
The click on properties and then in the shortcut tab go to
Start in and entering the desired path worked for me kindly note if IDLE is open and running while you do this you'll have to shut it down and restart it for this to work
If you locate the idlelib directory in your Python install, it will have a few files with the .def extension. config-main.def has instructions on where to put the custom config files. However, looking through these I did not find any configurable paths (your install may vary). Looks like you might need to crack open the editor code to alter it.
If you are using linux, you can create simple .sh file as presented below::
#!/bin/sh
cd /fullPath/PythonScripts/
idle
make the file executable by right click-> properties-> permissions-> check the execute as program checkbox-> done
Run the file :)
