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).

Function clean_duplicates_mro Undocumented
Function clean_typing_generic_mro 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.
Constant BUILTIN_DESCRIPTORS Undocumented
Constant EXCEPTION_BASE_CLASSES Undocumented
Constant ITER_METHODS Undocumented
Type Variable T Undocumented
Variable objects Undocumented
Class _ListComp Class representing an ast.ListComp node.
Function _c3_merge Merges MROs in sequences to a single MRO using the C3 algorithm.
Function _class_type return a ClassDef node type to differ metaclass and exception from 'regular' classes
Function _infer_decorator_callchain Detect decorator call chaining and see if the end result is a static or a classmethod.
Function _rec_get_names return a list of all argument names

def clean_typing_generic_mro(sequences: list[list[ClassDef]]): (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]
