Python - Functions with lists P51956

In this problem you must implement several functions on lists in Python.

1. Write a function myLength(L) that, given a list, returns its length.
2. Write a function myMaximum(L) that, given a non-empty list, returns its maximum.
3. Write a function average(L) that, given a non-empty list of numbers, returns its average.
4. Write a function buildPalindrome(L) that, given a list, returns the palindrome that starts with the reverse of the list.
5. Write a function remove(L1, L2) that, given a list L1 and a list L2, returns the list L1 after removing the occurrences of the elements in L2.
6. Write a function flatten(L) that recursively flattens a list whose elements may also be lists of different levels. Hint: use recursion and the isinstance(x, list) built-in function.
7. Write a function oddsNevens(L) that, given a list of integers, returns two lists, one with all the odd numbers and one with all the even numbers, in the same relative order than the original.
8. Write a function primeDivisors(n) that returns the list of all prime divisors of a non-zero positive integer.
