New submission from Camion <camion_spam-pyb...@yahoo.com>:
>>> help(sum) Help on built-in function sum in module builtins: sum(iterable, start=0, /) Return the sum of a 'start' value (default: 0) plus an iterable of numbers When the iterable is empty, return the start value. This function is intended specifically for use with numeric values and may reject non-numeric types. >>> sum([1, 2, 3], start=3) Traceback (most recent call last): File "<pyshell#11>", line 1, in <module> sum([1, 2, 3], start=3) TypeError: sum() takes no keyword arguments By the way, it is very annoying that the start value is not available, because it hampers the possibility to use sum with things like vectors. ---------- components: Interpreter Core messages: 339245 nosy: Camion priority: normal severity: normal status: open title: sum function's start optional parameter documented in help but not implemented type: behavior versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36491> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
