Introduction
In functional programming, currying is a technique of transforming a function that takes multiple arguments into a sequence of functions that each take a single argument. In Python, we can use the functools.partial() function to implement currying.
Curry Function
Write a function curry(fn, *args) that curries a given function fn. The function should return a new function that behaves like fn with the given arguments, args, partially applied.
from functools import partial
def curry(fn, *args):
return partial(fn, *args)
add = lambda x, y: x + y
add10 = curry(add, 10)
add10(20) ## 30
Summary
In this challenge, you learned how to implement a curry function using functools.partial() in Python. The curry function allows you to partially apply arguments to a function and return a new function that takes the remaining arguments.
