Need this with python

1. Assume that L is a list with one element. The element might be a number or it might be a list of one element, where that element might be a number or a list of one element, and so on. Return the innermost number. You must use recursion. Your solution cannot use a loop. Hint: type(52) == int is True. Test your program with the following: [5] [[55]] [[[123]]] [[[[[[[[[[[[18]]]]]]]]]]]]
