Question
What is the output of the following Python program?mylist = [ [2,4,1], [1,2,3], [2,3,5] ]total = 0for sublist in mylist: total += sum(sublist)print(total) Question 9Select one:a.14b.23c.0d.13
Solution
The output of the given Python program is 23.
Here's how:
The program defines a list of lists, and then iterates over each sublist in the list. For each sublist, it calculates the sum of the elements in the sublist and adds it to the total.
Here's the step-by-step breakdown:
- The first sublist is [2,4,1]. The sum of the elements in this sublist is 2 + 4 + 1 = 7.
- The second sublist is [1,2,3]. The sum of the elements in this sublist is 1 + 2 + 3 = 6.
- The third sublist is [2,3,5]. The sum of the elements in this sublist is 2 + 3 + 5 = 10.
When you add up the sums of each sublist, you get 7 + 6 + 10 = 23.
So, the output of the program is 23. Therefore, the correct answer is b. 23.
