Python: Multiply all the numbers in a given list using lambda

Python Lambda: Exercise-43 with Solution

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

Sample Solution:

Python Code :

from functools import reduce 
def mutiple_list(nums):
    result =  reduce(lambda x, y: x*y, nums)
    return result
nums = [4, 3, 2, 2, -1, 18]
print ("Original list: ")
print(nums)
print("Mmultiply all the numbers of the said list:",mutiple_list(nums))
nums = [2, 4, 8, 8, 3, 2, 9]
print ("\nOriginal list: ")
print(nums)
print("Mmultiply 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
