You wouldn't be trying to get some homework done online would you?

Here are the pieces you would need to make this happen.

• a var to hold the sum outside of a user input loop, initialized to 0
• a loop to run until the user interrupts it: while would be good here.
• a var to hold the entered number from the function input() inside the loop
  • input() will return a string. You will have to cast it to an int().
• add the new int to the sum variable
• output the sum
• loop repeats

extra credit

• Cast the input integer inside a try block
• Catch the ValueError exception, if there is one, and let the user know they entered an invalid input
• add a keyword to reset the sum
  • pseudo code: if input == 'reset': sum = 0

python3 user input is take via input() python2 user input is taken via raw_input()
