title: Python While Loop, also using modulo and continue commands
body: <p>Attempting to finish this task that asks me to: </p>
  
  <p>"Write a while loop that calculates the sum of the integers from 1 to 20 (inclusive), excluding those integers evenly divisible by 3. (Hint: You'll find the modulo operator (%) and the continue statement handy for this.)</p>
  
  <p>I've attempted to construct the code myself, but the evaluation of the code times out. I'm guessing my syntax is incorrect and is causing an infinite loop</p>
  
  <pre><code>    total, x = 0, 1
      while x &gt;=1 and x &lt;= 20:
          if x%3==0:
              continue
          if x%3 != 0:
              print(x)
              x+=1
              total+=1
      print(total)
  </code></pre>
  
  <p>The expected answer should be:</p>
  
  <p>20
  19
  17
  16
  14
  13
  11
  10
  8
  7
  5
  4
  2
  1</p>
  
  <p>But I just get 'Timed out' errors</p>
