In Python 3.8 the error message will be more informative:

SyntaxError: leading zeros in decimal integer literals are not
permitted; use an 0o prefix for o
A comment from the sideline: one could imagine extending the Python syntax
with a (optional) 0d prefix that allows for explicit specification of
decimal values. They would "complete" the family:
* 0b: binary number
* 0o: octal number
* 0d: decimal number
* 0x: hexadecimal number
I understand that
[[READERS DIGEST CONDENSED ANSWER: use int("string") ]]
Since we all agree python will not make notations like "05" work
indefinitely, and the need expressed is how to solve a symbolic puzzle (see
message below) then it makes sense to look at alternate representations.
I have a question first. Ho

Any particular reason?
Before Python 3, a leading 0 in an integer literal would indicate an
octal (base 8) number.
In Python 2.7:

That notation was borrowed

Not sure but I think that after 0 it expects x for hexadecimal, o for
octal, b for binary, ... may be others.
0xa
