Python: Sum two or more lists, the lengths of the lists may be different
Python List: Exercise - 194 with Solution
Write a Python program to sum two or more lists. The lengths of the lists may be different.
Sample Solution:
Python Code:
def sum_lists_diff_length(test_list):
result = [sum(x) for x in zip(*map(lambda x:x+[0]*max(map(len, test_list)) if len(x)<max(map(len, test_list)) else x, test_list))]
return result
nums = [[1,2,4],[2,4,4],[1,2]]
print("\nOriginal list:")
print(nums)
print("Sum said lists with different lengths:")
print(sum_lists_diff_length(nums))
nums = [[1],[2,4,4],[1,2],[4]]
print("\nOriginal list:")
print(nums)
print("Sum said lists with different lengths:")
print(sum_lists_diff_length(nums))
Sample Output:
Original list: [[1, 2, 4], [2, 4, 4], [1, 2]] Sum said lists with different lengths: [4, 8, 8] Original list: [[1], [2, 4, 4], [1, 2], [4]] Sum said lists with different lengths: [8, 6, 4]
