title: Can someone explain why var = input() in python doesn't work?
body: <blockquote>
    <p>You want to know your grade in Computer Science, so write a program
    that continuously takes grades between 0 and 100 to standard input
    until you input "stop", at which point it should print your average to
    standard output.</p>
    
    <p>NOTE: When reading the input, do not display a prompt for the user.
    Use the input() function with no prompt string. Here is an example:</p>
    
    <p>grade = input()</p>
  </blockquote>
  
  <pre><code>grade = input()
  count = 0
  sum = 0
  
  while grade != "stop":
      grade = input()
      sum += int(grade)
      count += 1
      print(sum / count)
  </code></pre>
  
  <p>Please dont solve it for me, but if you can point out why setting grade as "input()" doesnt work</p>
