How to undo sys.path.append(pathToModule)

Question

I have been trying to fix the python path on my cpu, and I originally was just trying to change my .bash_profile , but that wasn't working, so I used

import sys
sys.pat.append(path/To/Module)

and now when I run my script, I get this error message

How can I either fix this issue or undo the sys.path.append(path/To/Module) ?

Also, is it possible to export multiple directories in the python path, and if so how do I do that?

Answer 1

Note that if you add a path with sys.path.append() you do this only for the current session. No need to undo it.

Just remove the line from you python file.

Answer 2

Have you tried sys.path.pop()
That will remove the last item that you added or indeed the last item on the PYTHONPATH, whatever that might be.

Answer 3

How can I either fix this issue or undo the >sys.path.append(path/To/Module)?

To undo the sys.path.append , you just need to remove that line from your script. Since the path is only modified for your current script and not system wide until you edit the PYTHONPATH .

Also, is it possible to export multiple directories in the python path, and if so how do I do that?

If you want to do it using sys , you can do it like: sys.path.extend(['/path1', '/path2'])

recently I found that pycharm ide will automatically append certain directory to your sys.path if you marked that directory as Sources Root. So even if you use sys.path.pop(sys.path.index(**directory path**) , it wouldn't work. Just unmark the folder and the issue will be solved.
