43. Multiply Numbers in List Lambda

Write a Python program to multiply all the numbers in a given list using lambda.

Sample Solution:

Python Code :

# Import the 'reduce' function from the 'functools' module
from functools import reduce

# Define a function 'multiple_list' that multiplies all numbers in a list using 'reduce'
def mutiple_list(nums):
    # Use the 'reduce' function with a lambda to multiply all elements in the 'nums' list
    result = reduce(lambda x, y: x * y, nums)
    
    # Return the result of multiplying all numbers in the list
    return result

# Create a list 'nums' containing integers and one negative number
nums = [4, 3, 2, 2, -1, 18]

# Print the original list 'nums' and multiply all its numbers using 'multiple_list' function
print("Original list:")
print(nums)
print("Multiply all the numbers of the said list:", mutiple_list(nums))

# Create another list 'nums' containing integers
nums = [2, 4, 8, 8, 3, 2, 9]

# Print the original list 'nums' and multiply all its numbers using 'multiple_list' function
print("\nOriginal list:")
print(nums)
print("Multiply all the numbers of the said list:", mutiple_list(nums))

Sample Output:

Original list: 
[4, 3, 2, 2, -1, 18]
Mmultiply all the numbers of the said list: -864

Original list: 
[2, 4, 8, 8, 3, 2, 9]
Mmultiply all the numbers of the said list: 27648
