Python 2.7. Iterating list not working

Question

Just starting with Python and doing some challenges, this one on Collatz numbers. I am stuck at the start however, where the range that I am passing to the collatz method is not iterating over the given range.

What am I missing here?

def collatz(number):
    for i in number:
        if i % 2:
            return i // 2
        else:
            return 3 * (i + 1)


try:
    print(collatz(range(0,10)))
except ZeroDivisionError:
    print("Zero Division")
except TypeError:
    print "Type Error"

Answer 1

    for i in range(0,10):
        print(collatz(i))
