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

More general solution of Imanol Luengo from my point of view (python notebook example):

from functools import reduce
from functools import partial

def f(*argv, **kwargs):
  print('f: {} {}'.format(argv, kwargs))
  return argv, kwargs

def g(*argv, **kwargs):
  print('g: {} {}'.format(argv, kwargs))
  return argv, kwargs

def compose(fs, *argv, **kwargs):
  return reduce(lambda x, y: y(*x[0], **x[1]), fs, (argv, kwargs))

h = partial(compose, [f, g])
h('value', key='value')
output:
f: ('value',) {'key': 'value'}
g: ('value',) {'key': 'value'}

m = partial(compose, [h, f, g])
m('value', key='value')
output:
f: ('value',) {'key': 'value'}
g: ('value',) {'key': 'value'}
f: ('value',) {'key': 'value'}
g: ('value',) {'key': 'value'}
