Not quite true. Depending on the context, the obvious meanings of "_" in
Python are either

1) "ignore me", e.g. in

    _, b = some_tuple

or

2) "this is a non-public thing", as in

    class Xyz:
        _private = 1

or

3) "I am the translation function", as commonly used in (HTML) templates:

    _("translation key here")


None of the three meanings applies to the OP's example, AFAICT.
