Python is one of the most popular programming languages in the world today. In fact, it’s one of the most used programming languages across the globe. However, if you need to repeat N times in Python, then this blog will show you how to do that. Read on.
How Can You Repeat N Times in Python?
In many situations, we must carry out a series of operations on each element of an array, such as checking the text line by line, carrying out mathematic operations on every array value, or sorting a list or an array, among other things. For each of the mentioned activities, a section of the code must be repeated again. In Python, there are many ways to repeat N times but the most common and effective ways are utilizing itertools.repeat() method and range() function.
Option 1: Utilize intertools.repeat()
The itertools.repeat method is an unlimited iterator, it means that if the num
value, which denotes the whole number of iterations, is omitted, the procedure will continue to iterate indefinitely until the break
statement. This method’s val
parameter specifies the value which will be displayed after each iteration.
We will supply the value of N to the num
argument because we wish to repeat them N times, we will give a value of None
to the val
argument since we don’t need to print anything.
Python allows us to repeat N times because it simplifies the programming process. Let’s look at an example to learn more about this:
import itertools
num = 3
for _ in itertools.repeat(None, num):
print (num)
Result:
3
3
3
Option 2: Utilize range()
By using Python’s for
loop and range() method, we can repeat N times in Python. The function range(start, stop, step)
provides a list of numbers in ascending order from the start
argument value, which is always equal to 0
, through the stop
argument value. The range()
function returns a series with a step
size specified by the step parameter, which by default has a value of 1
. Let’s take a look at an example of this:
num = 2
for x in range(num):
print (num)
Result:
2
2
It also works in the following way:
for i in range(3):
print(i)
Result:
0
1
2
