Python | Tuple multiplication

Last Updated : 21 Nov, 2019

Sometimes, while working with records, we can have a problem in which we may need to perform multiplication of tuples. This problem can occur in day-day programming. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using zip() + generator expression
The combination of above functions can be used to perform this task. In this, we perform the task of multiplication using generator expression and mapping index of each tuple is done by zip().

# Python3 code to demonstrate working of 
# Tuple multiplication 
# using zip() + generator expression 
  
# initialize tuples 
test_tup1 = (10, 4, 5, 6) 
test_tup2 = (5, 6, 7, 5) 
  
# printing original tuples 
print("The original tuple 1 : " + str(test_tup1)) 
print("The original tuple 2 : " + str(test_tup2)) 
  
# Tuple multiplication 
# using zip() + generator expression 
res = tuple(ele1 * ele2 for ele1, ele2 in zip(test_tup1, test_tup2)) 
  
# printing result 
print("The multiplied tuple : " + str(res)) 

Output :

The original tuple 1 : (10, 4, 5, 6)
The original tuple 2 : (5, 6, 7, 5)
The multiplied tuple : (50, 24, 35, 30)

Method #2 : Using map() + mul
The combination of above functionalities can also perform this task. In this, we perform the task of extending logic of multiplication using mul and mapping is done by map().

# Python3 code to demonstrate working of 
# Tuple multiplication 
# using map() + mul 
from operator import mul 
  
# initialize tuples 
test_tup1 = (10, 4, 5, 6) 
test_tup2 = (5, 6, 7, 5) 
  
# printing original tuples 
print("The original tuple 1 : " + str(test_tup1)) 
print("The original tuple 2 : " + str(test_tup2)) 
  
# Tuple multiplication 
# using map() + mul 
res = tuple(map(mul, test_tup1, test_tup2)) 
  
# printing result 
print("The multiplied tuple : " + str(res)) 

Output :

The original tuple 1 : (10, 4, 5, 6)
The original tuple 2 : (5, 6, 7, 5)
The multiplied tuple : (50, 24, 35, 30)
