Convert for loop to recursive function in python3

Question

Is it possible to convert the following loop:

c = 0
for a in find:
    c += 1
return c

Where find is a list like [a,b,c,d] to a function that uses recursion without using external libraries?

Answer 1

def count(ls):
    if not ls:  # empty
        return 0
    return count(ls[1:]) + 1

Use it like this:

>>> find = [a, b, c, d]
>>> count(find)
