100_year = date.today().year - age + 100 ^ SyntaxError: invalid decimal literal

I'm trying to understand what the problem is.

Python identifiers can not start with a number.

The 'arrow' points to year because underscore is a valid thousands separator in Python >= 3.6, so 100_000 is a valid integer literal.

Sadly in python you cant make variables that start with numbers so therefore you could use something like this:

hundred_year = date.today().year - age + 100
