Wrong Python version in PyCharm's inspections

Question

Project Interpreter in PyCharm's settings for the project "Python 3.6 C:\Anaconda\python.exe"

But in my code I get inspections like "Python version 3.5 does not support a 'F' prefix"

There is no Python3.5 on my system anywhere, I tried to resolve this doing the following:

• removed the interpreter in pycharm settings, then added it back
• uninstalled all other python versions, deleted their entries from windows registry etc
• updated anaconda / conda etc

nothing is working. And anyway why does PyCharm show that the python version is 3.6 when I select it as the project interpreter, but that it is 3.5 in inspections?

Answer 1

Go to Settings->Editor->Inspections. There in Python->Code compatibility inspections, you should see that Python 3.5's box is ticked in.

This allows you to choose for which versions of Python your code will be inspected.

Answer 2

I totally agree with @Eskapp's answer, but here are a few additions that I had to do.

1. Press Ctrl + Alt + S OR Command + Option + S To open the Settings
2. Settings > Editor > Inspections > Python | Code compatibility inspection > Select the version(s) (In my case 3.7 and 3.8 and disselcting 2.7)
3. Settings > Project: | Project Interpreter > Make sure correct version and interpreter is selected.
4. File > Invalidate Caches / Restart...
5. Done.
