Answer to Question #43981 in Python for Gwen

Question

Write a program that repeatedly asks a user to enter a number. The program will sum up all the even number that the user keyed in. Terminate the program when the user enters -10, and display the sum of all the EVEN numbers entered by the user (exclude -10).

Please help the part, I have no idea how to do the sum of even number. But, other than that, I am able to do. Thank you.

Answer 1

number_list = []
while True:
  number_list.append(int(raw_input("Enter Number: ")))
  if number_list[-1] == -10:
    break
 
s = 0 #sum
for i in number_list[:-1]:
  if i % 2 == 0:
    s += i  
    
print "Sum of all the even numbers ", s
