Renaming function/class parameters should recognize calls done through functools partial

[baldassarreFe]

Renaming parameters of functions/classes is super useful and is - in my opinion - well implemented. The python extension automatically looks for all the places in the code where the function/class is called and applies the renaming accordingly.

However, the extension does not recognize calls that are made with functools.partial. As a consequence, when running the code, we get "TypeError: unexpected keyword argument".

Minimal example below:

Before:

from functools import partial

def foo(a: int, b: str):
    print(a, b)

def main():
    foo(a=1, b="hello")
    partial_foo = partial(foo, a=1)
    partial_foo(b="world")

if __name__ == "__main__":
    main()

Rename a to number:

After:

from functools import partial

def foo(number: int, b: str):
    print(number, b)

def main():
    foo(number=1, b="hello")
    partial_foo = partial(foo, a=1)  # <- Problem here!
    partial_foo(b="world")

if __name__ == "__main__":
    main()

The renaming feature is great, but it needs to work in 100% of the cases, otherwise I'm gonna be afraid of using it.

Btw, this works but it's ugly:

partial_foo = lambda *args, **kwargs: foo(*args, **kwargs, a=1)
