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.
