Multiply each element in a tuple by a number in Python

Multiply each element in a tuple by a number in Python #

To multiply each element in a tuple by a number:

1. Use a generator expression to iterate over the tuple.
2. On each iteration, multiply the current tuple element by the number.
3. Use the tuple() class to convert the generator object to a tuple.

Copied!
import math

my_tuple = (2, 4, 6)

# ✅ multiply each element in tuple by a number
result = tuple(num * 10 for num in my_tuple)

print(result)  # 👉️ (20, 40, 60)

# ---------------------------------

# ✅ multiply all elements in a tuple

result_2 = math.prod(my_tuple)
print(result_2)  # 👉️ 48

We used a generator expression to iterate over the tuple.

On each iteration, we multiply the current number by a different number and return the result.

The last step is to pass the generator object to the tuple() class.

The tuple class takes an iterable and returns a tuple object.

You might also see examples online that use a list comprehension instead of a generator expression.

my_tuple = (2, 4, 6)

result = tuple([num * 10 for num in my_tuple])

print(result)  # 👉️ (20, 40, 60)

List comprehensions are also used to perform some operation for every element, or select a subset of elements that meet a condition.

If you need to multiply all of the elements in a tuple, use the math.prod() function.

Copied!
import math

my_tuple = (2, 4, 6)

result_2 = math.prod(my_tuple)
print(result_2)  # 👉️ 48

The math.prod method calculates the product of all the elements in the provided iterable.

Copied!
import math

my_tuple = (5, 5, 5)

result = math.prod(my_tuple)

print(result)  # 👉️ 125

The method takes the following 2 arguments:

If the iterable is empty, the start value is returned.
