How to Repeat N Times in Python Using the itertools.repeat() FunctionPython’s itertools module provides another convenient function called repeat() to create an iterator that repeats elements from an iterable indefinitely.Syntax of the itertools.repeat() Functionitertools.repeat(element, times) ...

This will run n number of times the elements present in num Alternatively we can also use itertools to achieve the same, here is another example: import itertools num = 5 for _ in itertools.repeat(None, num): print(f"I will repeat myself {num} times") ...

Whenever we want to repeat a block of code a fixed number of times, the first way of doing it is using “for loops.” List comprehensions are also capable of doing the same and that too with a better approach than for loops since list comprehensions are more compact. Hence, it provides...
