This is the classic integer division problem with python2

In python2 temp /= 64 would perform integer division and so would result in truncated integer value. But your code would work fine in python3 as the division would result in a float

To fix it in python2, change temp /= 64 to temp /= 64.0, so that you would force getting the result as a float

This is the classic integer division issue

In python2 temp /= 64 would perform integer division and so your code would work fine. But it in python3, this would result in a float.

To fix the issue in python3, change temp /= 64 to temp //= 64 to force integer division and get rid of the temp = int(temp) line
