Invalid Token when using Octal numbers.

Question

Hi,

I'm a beginner in python and I'm trying to use a octal number in my script, but when I try it, it returns me that error:

>>> a = 010
SyntaxError: invalid token (<pyshell#0>, line 1)
>>> 01
SyntaxError: invalid token (<pyshell#1>, line 1)

There's something wrong with my code? I'm using Python3 (and reading a python 2.2 book)

Answer 1

Try 0o10, may be because of python 3, or pyshell itself.

PEP says,

octal literals must now be specified with a leading "0o" or "0O" instead of "0";

Answer 2

What is the version of Python? At least Python 2.6 process such statements correctly:

a=010
print a
8
