How to correctly set PYTHONPATH for Visual Studio Code

Question

How do I correctly set up the $PYTHONPATH variable for my workspace in VisualStudio Code?

Background Information

I have install

Answer 1

OP seemed to have asked about path syntax for the .env file and the vscode set up so that it finds and reads some custom module files. My problem was similar in that I wanted code to find my custom modules for import in a script. I did not want to put my custom modules in a folder inside my python environment. I also wanted to avoid setting one or more paths as PYTHONPATH for the User Variables in the Windows Environment Variables - but this will work if you want to do it. I am working in vscode in Windows 10.

1) SYNTAX:

a) I found that the following path syntax works in the env file:

PYTHONPATH = C:/0APPS/PYTHON/_MODULES

My .py module files are in this folder.

b) # works for comments in the .env file.

2) VSCODE SET-UP: I found that the following works:

a) Like sunew said at #2 My setup: Use the Explorer in vscode to open at your selected project workspace folder. For me that is Q:\420 PYTHON

b) Give the env file a name, like vscode.env file and place it in that folder at the top level of the workspace.

c) Open vscode settings and search .env where under the Extensions > Python you will find "Python: env file". Edit the box to add your env file name just before .env. e.g. ${workspaceFolder}/vscode.env

d) import custom_modulename now work for me - in the python interactive window and in a script.
