Why is this?
>>> 0000000000000000000000000000000 # No error
0
>>> 0000000000000000000000000000002
SyntaxError: leading zeros in decimal integer literals are not permitted; use an 0o prefix for octal integers

0000000000002 is not supported;
So 000000000000000 should not too.

[stevendaprano]

Its not a bug, it's deliberately designed that way. 0000 is not ambiguous: it's just zero, in any base. 0012 is ambiguous.

There's a recent thread about it here:

If you want to change the behaviour, your first step is to get a consensus on the mailing list that it should change.
