Python parser: `*` and `**` confusion

This is related to that comment

The Python parser seems to consider * and ** as modifier as specified there:

And never as arithmetic operator (but are ok as update operator) - although the grammar is defined there:

This is highlighted in the following snapshots in which modifier are bold green and operator purple


Is there a way to improve the parser to distinguish the two usages for * and **?

That was unintentional. This patch should help.

You are amazing :rocket: :heart:
