Hi I am troubling with this problem and I want to flatten a nested list. Here is my code but it does not work can someone help me please

def paps(lst):
    if lst == []:
        return lst
    if type(lst[0]) == list:
        return paps(lst[0])+ paps(lst[1:])
    else:
        return lst[:1] + paps(lst[1:])

My problem must be with recursion.

Your code is working for me. – Eli Sadoff Jul 02 '16 at 22:41
Can you put your output please – Luis Carlos Jul 02 '16 at 23:41
I ran it with `a=[1,[2,[3,[4,5]]]]` and got `[1,2,3,4,5]` as my result. – Eli Sadoff Jul 02 '16 at 23:48
