So i recently had a problem that regarded the command that is executed in vsc's integrated terminal every time the little triangular button on top right corner is pressed
It executes a command that consists of file path to python.exe file, and the currently selected file:
[path to current folder]>C:/Users/[username]/AppData/Local/Programs/Python/Python38-32/python.exe [currently selected file]
and i had problems with that, it didn't recognize some modules. So i found out if i do it by running the command python [currently selected file] it works flawlessly.
I found a setting in the python extension that is labeled python.pythonPath, which i edited from original to "python.pythonPath": "python", which i thought would work but it didn't. I have been digging trough the extention settings for some time now, and i have not been able to find this setting.
Is it even possible? Do i do it right? Is it even done by the python extention?
If you use cmd, it can run the Python files properly,it is recommended that you check whether the environment variables are correct. Reference:This.
To better run Python files in vscode, you could set up the vcode virtual environment.
As for the path 'python.pythonPath', you could refer to:pythonpath.

So I dont know what happened but my python files are not being executed by the command prompt.
C:/Users/MOHAMMED/Local/Programs/Python/Python39>button.py
Above is what im trying to do. but it keeps giving me errors.
This file does not have an app associated with it for performing this action.
I have been using cmd prompt everyday to execute python files but today it is not working. any help is appreciated.
(I use IDLE to do my code btw)
edit:
So this is what i do when im trying to execute files using cmd prompt.
I go into the directory of where all the python files are stored by using cd command.
2)then i just say the name of the file and it works.
but today i installed pip by using setup program and after pip was installed, i cant execute python file using cmd prompt.
You are trying to execute the wrong way it should be:
python button.py
If that doesn't work then :
The complete path of python.exe can be added by:
Right-clicking This PC and going to Properties.
Clicking on the Advanced system settings in the menu on the left.
Clicking on the Environment Variables button on the bottom right.
In the System variables section, selecting the Path variable and clicking on Edit. The next screen will show all the directories that are currently a part of the PATH variable.
Clicking on New and entering Python’s install directory.
Then again try :
python button.py
I have a PyCharm project on my Windows, where I am able to run most .py files by pressing Ctrl + Shift + F10 (or running the debugger). In one of the files however I get the error
Error running 'test':
Cannot run program "\opt\anaconda\bin\python" (in directory "..."): CreateProcess error=2, the system cannot find the file specified.`
The test.py file right now only contains print('hello')
I can do this for the other files, and using 'Execute selection in console' also works fine. Given I am on a Windows machine the "\opt\anaconda\bin\python" part looks suspicious, but I don't know how to fix it.
Any help?
Copying the content to another file (e.g. test_2.py) 'fixes' the problem, but since this is a collaborative project this isn't viable.
I think your case is cause by some project environment has changed.
I suggest your open the workspace.xml which located in .idea\, check the parameters in it.
or you can delete the directory ".idea" and re-create the project locate in the original path.
Hope it work
I had the same problem in PyCharm IDE and Windows after adding new libraries and some changes.
I recreated Run/Debug Configurations with these steps (Instead of recreating the whole of project!):
Select Edit Configurations... from top panel in PyCharm IDE
Select these files and press delete for deleting them
Recreate these files likes this images:
Click green arrow or press Ctrl + Shift + F10
This is what I had to do:
Check the .idea/workspace.xml for any old venv references (there are several tags like "SDK_HOME" which store the path to the venv) and update as necessary
Check the .idea/RunConfigurations for any run configs and update them (or delete and recreate as you like)
when I installed the pycharm I had the same issue. for this, you really need to understand the concept of the virtual environment. this error comes because you run the file in another directory in which you do not create any virtual environment.
let's say you create a virtual environment in any folder located at the desktop now you run the files in any other folder located in /user/AppData/any_folder then it will show the error that the system can't find the file specified.
So be sure you run in a file in the same folder in which you created a virtual environment.
I had the same problem after downloading a project from Github. It ended up being a configuration problem.
Creating a new project on Pycharm, pasting the code in it, and using your own configuration should solve the problem.
In Windows 8, I often use the Python Windows Launcher like
py C:/long/long/long/long/long/path/to/prog.py ...
Is there any way to set some environment setting, such as PATH or PYTHONPATH etc, to prevent having to type the full path to prog.py?
From my basic knowledge/research, PATH only helps with the py part of the command line and PYTHONPATH only helps with imports within prog.py, so how do I deal with the path to prog.py itself??
Notes:
I cannot modify the code, not even the "shebang" line, since it is needed to work on other platforms.
I cannot cd to the directory containing the programs to run them, because the programs will do something based on the directory they're run in (they'll modify the files in the directory they're run in).
I know that if I associate .py extension with the Python Windows Launcher, then I can run prog.py as the first item in the command line, and thus use PATH, but currently my .py extension is associated with my favorite editor and I'd like to keep it that way if possible (so I can double-click any Python file in Windows Explorer and edit it).
However, if someone suggests a solution where I can have a different association for Windows Explorer versus the command line, then that could be a potential solution! (i.e. in Windows Explorer, .py opens with the editor, while on command line, .py runs with Python Windows Launcher)
Add your long path to PYTHONPATH, then invoke your program as such:
python -m prog
Python will search for a module called prog and then run it as the main module.
Answer to my own question: Actually, I'm so silly. I could just set a variable for each program path (there are only a few programs paths), i.e.. prog=C:/long/path/to/prog.py and then do py %prog% .... I guess I figured out an answer to my own question that was acceptable to me.
Update: I just found something even better. I can do
doskey prog=py C:/long/path/to/prog.py $*
and then simply prog ... afterward
Now I just have to do some crazy stuff to get the doskey command into a file that will be run every time I start a console, as described here: https://stackoverflow.com/a/21040825/5182136
Yes, I've searched. So after spending about 4-5 hours struggling just to get Python files running, I recently stumbled over the solution to get it running through the environment variables like this: cmd -> python -> Python starts, yay yay
Since it didn't work to do it through the command line and similar I had to do it manually through the Windows interface. Now that it's working, however I cannot open .py files without typing out the full path like this: python C:\X\X\X\test.py which is obviously also starting to get annoying.
So now I'm trying to find out which variable I have to change (yet again) to only be able to type 'python test.py' and have it running. Sorry if I come off vague, but it's always a major pain to setup a new programming language for me and it kills my mood.
Thanks for help, it'll be really appreciated.
When you say
able to type 'python test.py'
I'm not sure exactly what you mean. Normally when the Python interpreter runs, it looks in the current directory for any source file that is named on the command line (unless you specifically name a location for the source file, as you've discovered). It seems from your previous statement:
python C:\X\X\X\test.py which is obviously also starting to get annoying
that your test.py file exists somewhere else.
What you might want to try is to change the current directory first, before running your script. In a command prompt window, type:
C:
cd \X\X\X
python test.py
(obviously substituting your actual path name). My apologies if you already know this.
To make python executable on your command line, you need to add it to your PATH environment variable, which it sounds like you have done on the command line. It is quite simple to add directories to the PATH in Windows if you know where to look. Essentially, you need to get to the Environment Variables dialog box, which is slightly different for each version of Windows.
For Windows XP: Start -> Control Panel -> System -> Advanced -> Environment Variables
For Windows Vista, 7: Click the Start Orb, right-click Computer and select Properties -> Advanced -> Environment Variables
Then, in the lower of the two boxes, find Path and click Edit. Change it so that C:\Python27 (or whichever version of Python you have) is at one end of the list, separated from the other entries by a semicolon (e.g. C:\Python27;C:\Program Files ...)
Once you've done this, python will work at the command line whenever you open a command window.
Regarding your second issue, however, there isn't much you can do. You must either specify the complete path to your script or already be in the same directory as the script. That is, if the script is in C:\X\X\X you will either need to invoke it as C:\X\X\X\test.py or first cd C:\X\X\X.
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 :)
