[FIXED] Match case - Invalid syntax with Spyder

Issue

I am using Spyder 5.3.1 and Python 3.10.4 within a virtual environment, on Windows 10. I know that with Python 3.10 came the match statement.

However, whenever I use the match keyword inside a script, the following error appears:

Code Analysis
Invalid syntax (pyflakes E)

But I can run the script correctly without any problem. So what can be the issue here?

Moreover, if I try directly in the IPython console, the match keyword is immediately recognized.

Solution

It's not so much an issue with Spyder as it is with the Pyflakes system it uses for linting code.

match is a new (soft) keyword in Python 3.10. Pyflakes 2.4.0 only supports up to Python 3.8 currently.

Pyflakes 2.5.0 is not out yet, but will cover up to Python 3.11, and should lint the new match keyword properly.
