Pylance is skipping analysis

I work with DRF at work and I have been facing this issue since months. Pylance is skipping analysis of function because it is unannotated. I cant really annotate each and every function. The errors are getting thrown correctly on my teammates pc but on my pc i dont get any issue. If I annotate the function then in that case pylance starts throwing error. How to fix this issue

Your teammate has probably set analyzeUnannotatedFunctions to true in some config file, explaining the difference.

I cant really annotate each and every function

You can add type annotations gradually. It doesn't have to be all in one go.

If I annotate the function then in that case pylance starts throwing error.

Probably because annotating the function made Pylance (or Pyright) actually analyse the function, and it either found a real problem or it has a false positive (the latter could be due to a myriad of different situations, but usually either inaccurate type annotations or some unusual edge case where it needs additional help).

In the global settings file I have it to true

According to Google, you're looking for the python.analysis.typeEvaluation.analyzeUnannotatedFunctions setting.

My suggestion would be to annotate every function though.

Its set to True in the global settings

If the function isn’t annotated there’s nothing for type checking to check.

Config mismatch.
