Power operation in Python [duplicate]

Question

I was playing around with Python. I had a doubt about the power operation in Python. So, I tried this:

0726**13 = 54609997061205831773270000000000000L 
726**13 = 15565965698792536237226936270158258176L

Why is there a difference between these two? I know it might be trivial. But, I could not figure it out. Could someone please explain? Thanks.

Answer 1

It's because an integer constant beginning with 0 is taken to be an octal value. In this case, 0726 is interpreted as 470:

>>> 0726
470
>>> 470**13
54609997061205831773270000000000000L
