Python | Multiply elements of Tuple

Last Updated : 11 Dec, 2019

Given, a list of tuples, the task is to multiply the elements of the tuple and return list of the multiplied elements.

Examples:

Input: [(2, 3), (4, 5), (6, 7), (2, 8)]
Output: [6, 20, 42, 16]
Input: [(11, 22), (33, 55), (55, 77), (11, 44)]
Output: [242, 1815, 4235, 484]

There are multiple ways to multiply elements of a tuple. Let’s see a couple of them.

# Method 1: Using Iteration
This is the most naive method to achieve a solution to this task. In this, we iterate over the whole list of tuples and multiply the elements in each tuple to get the list of elements.

# Python code to convert list of tuple into list of elements
# formed by multiplying elements of tuple.
  
# Input list initialisation
Input = [(2, 3), (4, 5), (6, 7), (2, 8)]
  
# Output list initialisation
Output = []
  
# Iteration to multiply element and append multiplied element in 
# new list
for elem in Input:
    temp = elem[0]*elem[1]
    Output.append(temp)
  
# printing output
print("The original list of tuple is ")
print(Input)
  
print("\nThe answer is")
print(Output)

Output:

The original list of tuple is 
[(2, 3), (4, 5), (6, 7), (2, 8)]

The answer is
[6, 20, 42, 16]

# Method 2: Using list comprehension
This is the one-liner approach to achieve the solution to this task.

# Python code to convert list of tuple into list of elements
# formed by multiplying elements of tuple.
  
# Input list initialisation
Input = [(2, 3), (4, 5), (6, 7), (2, 8)]
  
# Iteration to multiply element and append multiplied element in 
# new list
Output = [(x * y) for x, y in Input]
  
# printing output
print("The original list of tuple is ")
print(Input)
  
print("\nThe answer is")
print(Output)

Output:

The original list of tuple is 
[(2, 3), (4, 5), (6, 7), (2, 8)]

The answer is
[6, 20, 42, 16]
