Language/Type: Python recursion return

Write a recursive function named even_digits that accepts an integer parameter n and returns a new integer containing only the even digits from n, in the same order. If n does not contain any even digits, return 0.

For example, the call of even_digits(8342116) should return 8426 and the call of even_digits(35179) should return 0.

Function: Write a Python function as described, not a complete program.
