title: Count how many times while loop was used
body: <p>so i build a simple while loop to check how many blows needed to cool down the tea. One blow reduces the tea temperature by 10C. The problem is that I have no idea how to go forward with this. I know its something simple but just started python. Thanks</p>
  
  <pre><code>tea = 100 #temperature of tea to start with
  while tea &gt;= 70:
      print (str(tea) + " C")
      tea = tea - 10
  print (" It's ready now ... ")
  </code></pre>
