Unable to debug Python in VScode

Question

Whenever I try to debug any python code in VScode (or even visual studio), I run into errors before it reaches the first line of code (or so it would seem). I was able to debug in both VScode and Visual Studio ~18hrs ago on both my laptop and my desktop computers before taking a break. As of ~4hrs ago, I kept running into the errors when trying to run the debug. I am able to run code through python.exe without a problem through the cmd.exe C:\Python\Python37-32\python.exe C:\Coding\Codecademy\Python\one.py.

I have tried uninstalling VScode, Visual Studio, and python, as well as deleted all files pertaining to any VScode or Visual studio. I then reinstalled VScode and python 3.7, though the errors still occur in the terminal. This occurs even with a simple print("Hello World").

I am currently using the Python extension from Microsoft with no other extensions installed.

The error code is as follows:

Update: The problem still persists, but I've noticed another area where it seems to throw an similar error regarding python (relating to the 'Queue' object). Whenever I try to install a linter, it throws the following error in the terminal:

Answer 1

If this helps anyone, I had a situation where all of a sudden my Python code didn't seem to be debugging In VS Code anymore. There would be a brief change of color in the status bar at bottom and that's all. It turned out to be due to a blank line accidentally getting inserted into the code before the line containing "main()". I removed it and voila!

Answer 2

Try checking your python version I faced similar errors when I was trying to run my python3 code in VScode. Try changing the python version in vscode.
