Can anyone explain what functools.partial do?

Answer 1

partial() can be used to sort of hard-code some default arguments when calling a function.
I meddled with it in this code:

It could be useful also if you have a function that takes two arguments, and you have to use it in a situation where a function with a single argument is expected, as in parameter of higher order functions like filter, map, reduce.

Answer 2

I did got some examples but not clear yet. I understand it shortens some effort by merging key args?
