astroid.nodes.scoped_nodes.scoped_nodes

module documentation
(source)

This module contains the classes for "scoped" node, i.e. which are opening a new local scope in the language definition : Module, ClassDef, FunctionDef (and Lambda, GeneratorExp, DictComp and SetComp to some extent).

def clean_typing_generic_mro(sequences): (source)

A class can inherit from typing.Generic directly, as base, and as base of bases. The merged MRO must however only contain the last entry. To prepare for _c3_merge, remove some typing.Generic entries from sequences if multiple are present.

This method will check if Generic is in inferred_bases and also part of bases_mro. If true, remove it from inferred_bases as well as its entry the bases_mro.

Format sequences: [[self]] + bases_mro + [inferred_bases]
