os.chmod('myfile', 0777)

Python will recognise integers written in octal if you leave a
leading zero, and in hex if you use a leading 0x or 0X.

>>> 010
8
>>> 0x10
16
>>> 010 + 0x10
24

As John pointed out, you don't have to use octal for chmod. You can use
decimal, or hex -- anything that is an integer.
