In Python, you can repeat a string "
n" number of times without using a loop, in the following ways:
Using Repetition Operator
Perhaps the simplest way to repeat a string "
n" number of times in Python is to use the repetition operator (
*), for example, like so:
foo = 'quack!' * 3 print(foo) # "quack!quack!quack!"
You can also use
*= to achieve the same:
foo = 'quack!' foo *= 3 print(foo) # "quack!quack!quack!"
str.join() method takes an iterable as an argument:
Therefore, to repeat a string "
n" number of times, you can simply pass
itertools.repeat() as an argument to it, for example, like so:
import itertools as it foo = ''.join(it.repeat('quack!', 3)) print(foo) # "quack!quack!quack!"
This works because the
itertools.repeat() method creates an iterator that returns the same string repeated a specified number of times, which the
str.join() method joins together using the empty string as a separator.
