title: not all arguments converted during string formatting.. NO % variables
body: <pre><code>x = input()
  y = 1 
  print (x)
  while 1 == y:
  if x == 1:
      y == y + 1
  elif x % 2 == 0: #even
      x = x // 2
      print (x)
  else:
      x = 3 * x + 1
      print (x)
  </code></pre>
  
  <p>If you know what the Collatz conjecture is, I'm trying to make a calculator for that. I want to have x as my input so I don't have to change x's number and save every time I want to try out a new number. </p>
  
  <p>I get below error </p>
