Python: Tips of the Day

Performs right-to-left function composition:

Example:

from functools import reduce

def tips_compose(*fns):
  return reduce(lambda f, g: lambda *args: f(g(*args)), fns)
add6 = lambda x: x + 6
multiply = lambda x, y: x * y
multiply_and_add_6 = tips_compose(add6, multiply)

print(multiply_and_add_6(10, 3))

Output:
