title: How can I simplify this code in python?
body: <p>The task is to get all the multiples of 3 below 100, and then add them together.</p>
  
  <pre><code>num1 = 0
  l = []
  while num1 &lt; 100:
      num1 = num1 + 3
      l.append(num1)
  # I used this to delete the last element in the list which is 102,
  del l[-1]
  print l
  # sum of all the numbers in l
  b = sum(l)
  print b
  </code></pre>
