bpo-33371: Clarify the inspect.getmembers predicate parameter by briancurtin · Pull Request #6615 · python/cpython
Previously, the predicate parameter was mentioned, but what it was to be called with was not documented and required either trial-and-error or looking into the source to find that it is called with the value, or second item, of the full members list. This change addresses what the predicate callable will receive, as well as does some light formatting to make this clear.
