Question

The following code generates a list arr with 100 items.

import random

random.seed(0)

arr = [ random.randint(1,100) for _ in range(100) ]

Write a program that computes the sum of squares of all the numbers in the list arr

Submit both the code and result (sum of squares of all the numbers in arr)

Answer 1

Implement the program as follows:

1. import random module
2. Initialize random module for generating random values
3. create a list, arr and initialize it with 100 random values
4. print list, arr
5. initialize sum_of_squares to 0
6. for each value in arr list
7. calculate square of value as value*value and add it to sum_of_squares
8. print sum_of_squares

import random                                       # import random module
random.seed(0)                                      # Initialize random module for generating random values 
arr = [ random.randint(1,100) for _ in range(100) ] # create a list, arr and initialize it with 100 random values

print("List arr :")
print(arr)                                          # print list, arr

sum_of_squares = 0                                  # initialize sum_of_squares to 0
for value in arr:                                   # for each value in arr list
    sum_of_squares += value*value                   # calculate square of value as value*value and add it to sum_of_squares
    
print("Sum of squares = " + str(sum_of_squares))    # print sum_of_squares
