I recently learned about functools.partial. I understand it is meant for currying functions. It seems to me its awfully similar to how I've used closures many times in Python. I often write closures to capture or fix some parameters in a function (as shown below). But I've read online that curried functions and closures are not the same thing. Given that, I am trying to understand where one might use partial instead of writing a closure using function or a lambda. Consider the simple example below. Here it seems they aren't much different. Can anyone provide a motivating example where partial is needed to solve a problem that a regular function or a lambda expression closure cannot? from functools import partial def func(a, b, c): return a * b + c funcC = partial(func, 1, 2) funcC_alt = lambda c: func(1, 2, c) funcC(5) # 7 funcC_alt(5) # 7 Continue reading...
