Composing functions in python

Question

I have an array of functions and I\'m trying to produce one function which consists of the composition of the elements in my array. My approach is:

def compo         


        

Answer 1

I prefer this one due to readability/simplicity

from functools import reduce

def compose(*fs):
   apply = lambda arg, f: f(arg)
   composition = lambda x: reduce(apply, [x, *fs])
   return composition

the pipe = compose(a, b, c) will first apply a, then b and then c.

With regard to maintainability (an debugging) I think actually this one is the easiest to use:

def compose(*fs):
    def composition(x):
        for f in fs:
            x = f(x)
        return x
    return composition
