How to solve error in Python 2.7 tuple?

Question

Python

Friends, help me figure it out! Refuses to execute the following code:

s = {
    'param': ( (01,09,2005), (u'other') )
    }

actually the error itself:

File "C:/.../test.py", line 130
    'param': ( (01,09,2005), (u'other') )
                    ^
SyntaxError: invalid token

Interestingly, it swears only at the numbers 8 and 9 , everything is done with the rest.
What could be wrong?

Thanks everyone! Issue resolved.

Answer 1

Because this is an octal number that starts with 0 in Python, and there are no 8 and 9 in the octal number system.
