This is not a bug: See 
http://docs.python.org/ref/integers.html for an explanation. 
Numbers starting with '0' are considered octal, and there is no 
digit '8' or '9' in octal.

This is not a bug.

Numbers that start with digit 0 are interpreted as octal.  8
and 9 are not legal octal digits, so 08 and 09 are not legal
tokens.

See section 2.4.4 of the Python Language Reference.
