[Python-ideas] Function to apply superset of arguments to a function

[Andrey Fedorov]

Hi all,

I've written a function [1] called apply_some which takes a set of keywords
arguments, filters only those a function is expecting, and calls the
function with only those arguments. This is meant to suppress TypeErrors - a
way to abstract the logic which checks what arguments a passed-in function
accepts.

For example:

def foo(x=1, y=2):
    return (x,y)

apply_some(foo, y=0, z="hi") // calls foo(y=0)
-> (1,0)

I'd like to expand this to fill undefined arguments with None, but before I
do, does anyone know of any packages/libraries which either do something
similar or would make this code cleaner?

Cheers,
Andrey
