4.9 Code Practice: Question 1

The program sums all the values in a given range and assigns the total to the sum variable. The program is written in python 3 thus :

sum = 0

#initialize a sum variable, initialized as 0

for x in range(3, 67, 3):

#loop through the range taking a step of 3 after each iteration.

sum+= x

#add the iterated value to the sum variable after each iteration

print(sum)

#display the sum

A sample run of the program is attached

total = 0

for x in range(3, 67, 3):

   total += x

print(total)
