How do I call a function twice or more times consecutively?

Question

Is there a short way to call a function twice or more consecutively in Python? For example:

do()
do()
do()

maybe like:

3*do         


        

Answer 1

You can use itertools.repeat with operator.methodcaller to call the __call__ method of the function N times. Here is an example of a generator function doing it:

from itertools import repeat
from operator import methodcaller


def call_n_times(function, n):
    yield from map(methodcaller('__call__'), repeat(function, n))

Example of usage:

import random
from functools import partial

throw_dice = partial(random.randint, 1, 6)
result = call_n_times(throw_dice, 10)
print(list(result))
# [6, 3, 1, 2, 4, 6, 4, 1, 4, 6]
