int('0600',8) will do, but why would you want to do that?

Any of
x = 0600
x = 384
x = 0x180
x = int('0600',8)
will bind x to the same value (110000000 in binary if you care).

But once you've got the valued defined, through whatever human readable 
representation you want, the command
chmod(filename, x)
can be issued without further thought.
