Evgeny Kapun added the comment: There are methods that accept a single argument and behave like a binary operation or a predicate. It would be useful to be able to turn them into binary functions for use with higher-order functions like map and reduce:
reduce(methodcaller("combine"), objs) # reduce a sequence using "combine" method map(methodcaller("combine"), alist, blist) # combine pairs of elements all(map(methodcaller("compatible_with"), alist, blist)) # check that pairs of elements are compatible This functionality is already available for overloaded operators, because operator module provides them as functions. Some methods behave similarly to operators, so I think that a similar functionality should be available for them as well. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25454> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
