Python Data Structures and Algorithms - Recursion: List sum
Python Recursion: Exercise-3 with Solution
Write a Python program of recursion list sum.
Sample Solution:
Python Code:
def recursive_list_sum(data_list):
total = 0
for element in data_list:
if type(element) == type([]):
total = total + recursive_list_sum(element)
else:
total = total + element
return total
print( recursive_list_sum([1, 2, [3,4],[5,6]]))
Sample Output:
21
