title: "<=" not giving expected results in Python
body: <p>I am teaching myself Python. I have gone through some tutorials and thought I'd write a little program for counting the candles for each of the respective 8 nights of Hanukkah.</p>
  
  <pre><code>days = 0
  candles = 1
  
  while days &lt;= 8 :
      days = days + 1
      candles = candles + 1
      print ("Day", days,":", candles, "Candles")
  </code></pre>
  
  <p>But the results for this (Python 3.4) are:</p>
  
  <pre><code>Day 1 : 2 Candles
  Day 2 : 3 Candles
  Day 3 : 4 Candles
  Day 4 : 5 Candles
  Day 5 : 6 Candles
  Day 6 : 7 Candles
  Day 7 : 8 Candles
  Day 8 : 9 Candles
  Day 9 : 10 Candles
  </code></pre>
  
  <p>Why didn't it stop at day 8?</p>
