Before Python 3, a leading 0 in an integer literal would indicate an
octal (base 8) number.
So, the reason is historical.
The old form is now invalid in order to reduce the chance of bugs.
I encounter this problem on trying to do something like this:
eval('03 + 00 + 15')
It takes me some efforts to get rid of those leading zeros:-(
Hope someday 03 can be accepted as a valid decimal number in Python 3.
Thank you for explaining.

I'd say we *really* don't want that. We'd have old C programmers (like
me) expecting 010 to mean 8, and getting really confused...
We could just wait until all the old C programmers have died. :-)
