Python recursive function doesn't return

Question

I\'m trying to sharpen my noob Python skills by trying a problem my son has in his college CS class. The goal is to create a function that uses recursion to process a list. The

Answer 1

The problem is that you don't actually do a recursion (every call to the same function returns the result) but since lists are mutable you don't need to:

def ProcessList(ListIn):
    RecursiveProcess(ListIn, len(ListIn)-2) #this will change the list in place!
    return ListIn

that's all to get it working like expected. Because each element is updated in the "recursion" so there is no need to pass the pointer to the list around. And also the result is what is expected:

# [59, 54, 44, 33, 27, 20, 19, 17, 13, 7]
