So *if* we were to add anything to the language here, it would be to add `itertools.repeat_call` as a new iteration primitive, since it isn't entirely straightforward to construct that operation out of the existing primitives, with itertools.starmap coming closest:
def repeat_call(callable, n): yield from starmap(callable, repeat((), n))
But the explicit for loop being clearest:
def repeat_call(callable, n): for __ in range(n): yield callable()
It occurred to me to check whether or not `more_itertools` already had a suitable operation here, and it does: https://more-itertools.readthedocs.io/en/latest/api.html#more_itertools.repe... This is the `repeatfunc` recipe from the itertools documentation: https://docs.python.org/3/library/itertools.html#itertools-recipes Cheers, Nick. -- Nick Coghlan | ncoghlan@gmail.com | Brisbane, Australia
