Enable --check-untyped-defs for MyPy

[WillAyd]

As brought up in a conversation with @simonjayhawkins we might want to consider adding --check-untyped-defs to the mypy config file. Right now unannotated functions are skipped so local variable inference and checking is not done until an annotation is added. Working through this flag in advance may lead to less surprises as annotations are added

Note that this can also be enabled globally and per module, so we could prioritize as needed. Docs here:

https://mypy.readthedocs.io/en/latest/config_file.html#untyped-definitions-and-calls

Here are failures currently on master. I haven't looked in detail but assume that the degree of difficulty to resolve will vary. PRs to tackle individual modules may be best

@vaibhavhrt something you may have interest in as well

[vaibhavhrt]

Yeah, but I still am trying to complete annotating DataFrame. Not getting much time after freelancing as well as working whole day at my full-time job. 😌
Still I will try to find some time for this too. We might need a master tracker issue (or just use this one) with some checklist of todo modules.

[vaibhavhrt]

Will look into it after closing #26766 as I feel 26766 should have a higher priority. Also lot of issues from ☝️ will get resolved in 26766.

[WillAyd]

Sure but I think for general contributors would take PRs for these whenever

[vaibhavhrt]

Yeah, lot of work in typing, we will need more contributers.

[vishwakftw]

@WillAyd Could I work on this issue?

[WillAyd]

Sure. I would suggest picking one module to fix for now and submitting a PR for that

[simonjayhawkins]

Here are failures currently on master. I haven't looked in detail but assume that the degree of difficulty to resolve will vary. PRs to tackle individual modules may be best

no of errors for the relevant modules..
