Function is_python_space 

pub fn is_python_space(c: char) -> bool

Python’s str.isspace(), str.strip(), and \s on a str pattern.

One set of 29 code points, verified identical across all three on 3.10 and 3.13: the Unicode White_Space property plus the four C0 separators U+001C-U+001F. Rust’s char::is_whitespace is White_Space alone, 25 points, so str::trim is not str.strip() and is never used to port it.

Written out rather than delegated to char::is_whitespace plus the four, because this predicate decides parity and should not depend on which Unicode version the compiler shipped with. python_whitespace_matches_rusts_view below is the drift detector for that choice.
