Performs left-to-right function composition.
Use functools.reduce() to perform left-to-right function composition.
The first (leftmost) function can accept one or more arguments; the remaining functions must be unary.
from functools import reduce
def compose_right(*fns):
return reduce(lambda f, g: lambda *args: g(f(*args)), fns)
add = lambda x, y: x + y
square = lambda x: x * x
add_and_square = compose_right(add,square)
add_and_square(1, 2) # 9
