Repeating tuples N times

We are given a tuple with integer values and an integer N. We need to create a Python program to create a new tuple that will contain the given tuple repeated N times.

Input:
tup1 = (2, 9), N = 5

Output:
((2, 9) ,(2, 9) ,(2, 9) ,(2, 9) ,(2, 9))

To create duplicate tuples N times, we need to create an empty tuple and concatenate the values of the tuple to it N times. Python provides some methods that can help to ease the programmer's work performing these tasks, let's learn them here.

Method 1:

One method to perform the task is by using the multiplication operator "*" which will multiply the tuples and create a new tuple with the values the tuple repeated N times.

# Python program to repeat tuples N times
  
# Initializing and printing tuple 
myTup = (32, 8)
print("The elements of the given tuple are " + str(myTup))
N = 4
  
# Repeating Tuple N times
repeatTuple = ((myTup, ) * N)
  
# printing result
print("The tuple repeated N times is : " + str(repeatTuple))

Output:

The elements of the given tuple are (32, 8)
The tuple repeated N times is : ((32, 8), (32, 8), (32, 8), (32, 8))

Method 2:

Another method to solve the problem is by using the repeat() method present in Python's itertools library. This will return a list consisting of the tuple repeated N times. Then we will convert it into a tuple using the tuple() method.

# Python program to repeat tuples N times
  
import itertools
  
# Initializing and printing tuple 
myTup = (32, 8)
print("The elements of the given tuple are " + str(myTup))
N = 4
  
# Repeating Tuple N times
repeatTuple = tuple(itertools.repeat(myTup, N))
  
# Printing result
print("The tuple repeated N times is " + str(repeatTuple))

Output:

The elements of the given tuple are (32, 8)
The tuple repeated N times is ((32, 8), (32, 8), (32, 8), (32, 8))
