Tuple multiplication in Python

When it is required to perform tuple multiplication, the 'zip' method and the generator expression can be used.

The zip method takes iterables, aggregates them into a tuple, and returns it as the result.

Generator is a simple way of creating iterators. It automatically implements a class with '__iter__()' and '__next__()' methods and keeps track of the internal states, as well as raises 'StopIteration' exception when no values are present that could be returned.

Below is a demonstration of the same −

Example

my_tuple_1 = (23, 45, 12, 56, 78)
my_tuple_2 = (89, 41, 76, 0, 11)

print("The first tuple is : ")
print(my_tuple_1)
print("The second tuple is : ")
print(my_tuple_2)

my_result = tuple(elem_1 * elem_2 for elem_1, elem_2 in zip(my_tuple_1, my_tuple_2))

print("The multiplied tuple is : ")
print(my_result)

Output

The first tuple is :
(23, 45, 12, 56, 78)
The second tuple is :
(89, 41, 76, 0, 11)
The multiplied tuple is :
(2047, 1845, 912, 0, 858)

Explanation

  • Two tuples are defined, and are displayed on the console.
  • They are zipped, and iterated through
  • Every element from first tuple is multiple with the corresponding element in the second tuple.
  • It is converted to a tuple.
  • This operation is assigned to a value.
  • It is displayed as output on the console.
