Question
Design a Pythonprogram to prime the sum of all the even numbers from 1 to 20.
Expert Solution
Step 1
Programming approach:
- Set the lower limit to 1.
- Set the upper limit to 20.
- Set total to 0.
- Iterate each number in the list from lower to upper limit using for loop:
- Check if the number is even then
- Print Number.
- Update total by adding the previous value of the total to the current number.
- Check if the number is even then
- Print total.
Step 2
The following python program that prints the sum of all the even numbers from 1 to 20:
#set lower limit to 1
low = 1
#set higher limit to 20
high = 20
#set total to 0
total = 0
# iterate each number in list
for number in range(low, high + 1):
#check if number is even
if number % 2 == 0:
print(number)
#update total for every number
total = total + number
print("The sum of even numbers from 1 to 20 is",total)
