How do you find the sum of a list in Python?

Approach :

1. Read input number asking for length of the list using input() or raw_input() .
2. Initialise an empty list lst = [] .
3. Read each number using a for loop .
4. In the for loop append each number to the list.
5. Now we use predefined function sum() to find the sum of all the elements in a list.
6. Print the result.

How do you find the average of all elements in a list?

Average of the list is defined as the sum of the elements divided by the number of the elements. In this method, we will iterate over the list of and will add each element to a variable count which stores the sum of the ith element and then dividing the sum with the total number of variables to find the average.

How do you find the sum of an average?

The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set. For example, suppose we want the average of 24 , 55 , 17 , 87 and 100 . Simply find the sum of the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5 to get 56.6 .
