Python: Find the specified number of largest products from two given list, multiplying an element from each list

Python List: Exercise - 190 with Solution

Write a Python program to find the specified number of largest products from two given list, multiplying an element from each list.

Sample Solution:

Python Code:

def top_product(nums1, nums2, N):
    result = sorted([x*y for x in nums1 for y in nums2], reverse=True)[:N]
    return result
nums1 = [1, 2, 3, 4, 5, 6]
nums2 = [3, 6, 8, 9, 10, 6]
print("Original lists:")
print(nums1)
print(nums2,"\n")
N = 3
print(N,"Number of largest products from the said two lists:")
print(top_product(nums1, nums2, N))
N = 4
print(N,"Number of largest products from the said two lists:")
print(top_product(nums1, nums2, N))

Sample Output:

Original lists:
[1, 2, 3, 4, 5, 6]
[3, 6, 8, 9, 10, 6] 

3 Number of largest products from the said two lists:
[60, 54, 50]
4 Number of largest products from the said two lists:
[60, 54, 50, 48]
