How to fix that weird syntax coloration of Python 3.11 code on VS Code?

Question

I'm encountering a syntax coloration issue on VS Code. I don't know if this my VS Code that cannot handle Python 3.11 or it's an issue with my syntax coloration.

For example, this code:

from FcpeApp.models import User
from FcpeApp.models import Admin
from FcpeApp.models import Supervisor

from passlib.hash import sha256_crypt

class PasswordManager : 
    
    @staticmethod
    def generate(obj : User|Admin|Supervisor, pwd : str) -> None :
        obj.password = sha256_crypt.hash(pwd)
        obj.save()
        
    @staticmethod
    def verify() :
        pass

This shows up in VS Code as:

Here, the second def is not colored like the first def, but, for me, the code is correct.

I tried to reload my IDE, re-install my theme (one dark theme), change my theme to another theme (monokai dimmed), but the problem still exists and it is very to hard to work in this type of code without correct syntax coloration features.

I'm using the tht13.python extension.

Answer 1

The issue was found by extension bisect to be caused by the tht13.python, which is deprecated (see Python for VS Code installation problem: "This extension is deprecated as it is no longer being maintained." for more info on that deprecation). I suggest to use Microsoft's Python extension instead ^{_{(I have no affiliation with this extension)}}.
