"""
categories: Syntax,Literals
description: MicroPython requires spaces between literal numbers and keywords or ".", CPython doesn't
cause: Different parser implementation
MicroPython's tokenizer treats a sequence like ``1and`` as a single token, while CPython treats it as two tokens.
Since CPython 3.11, when the literal number is followed by a token, this syntax causes a ``SyntaxWarning`` for an "invalid literal". When a literal number is followed by a "." denoting attribute access, CPython does not warn.
workaround: Add a space between the integer literal and the intended next token.
This also fixes the ``SyntaxWarning`` in CPython.
