If more than one sequence is given, the function is called with an argument list consisting of the corresponding item of each sequence, substituting None for missing values when not all sequences have the same length. If the function is None, return a list of the items of the sequence (or a list of tuples if more than one sequence). Test cases: >>> oldmap(None, 'hello world') ['h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd'] >>> oldmap(None, range(4)) [0, 1, 2, 3] More test cases are in test_past.test_builtins. r Nc S s g | ] }t |��qS r )�len)�.0�itemr r r � <listcomp>X s zoldmap.<locals>.<listcomp>r ) � itertools� zip_longestr r r �maxr r � TypeError)�func� iterablesZzipped�l�result�er r r �oldmap8 s r' c O s t tj| |��S )N)r r �range)r �kwargsr r r �oldrange� s r* c O s t tj| |��S )N)r r �zip)r r) r r r �oldzip� s r, )�reducer r r( r- r+ )�__doc__� __future__r r r r r r Z past.typesr Z past.utilsr r r r r' r* r, r r r( � functoolsr- r+ �__all__� __builtin__r r r r �<module> s4 D
