How to know if a list has an even or odd number of elements

Question

How can I find out if there is even, or odd, number of elements in an arbitrary list.

I tried list.index() to get all of the indices... but I still don\'t k

Answer 1

All you need is

len(listName)

Which will give you the length.

I guess you could also do this then

if len(listName) % 2 == 0:
    return True  # the number is even!
else:
    return False # the number is odd!
