def ilookup(self, name): (source)

Lookup the inferred values of the given variable. :param name: The variable name to find values for. :type name: str :returns: The inferred values of the statements returned from :meth:`lookup`. :rtype: iterable

@lru_cache()
def lookup(self, name: str) -> tuple[LocalsDictNodeNG, list[NodeNG]]: (source)

Lookup where the given variable is assigned. The lookup starts from self's scope. If self is not a frame itself and the name is found in the inner frame locals, statements will be filtered to remove ignorable statements according to self's location. :param name: The name of the variable to find assignments for. :returns: The scope node and the list of assignments associated to the given name according to the scope where it has been found (locals, globals or builtin).
