title: Multiplying several variables in python
body: <p>My code is as follows:</p>
  
  <pre><code>box = raw_input('What is your box size')
  
  op1 = float(box)*602,216,900,000,000,000,000,000
  
  op2 = op1 * 1,000
  
  print op2
  </code></pre>
  
  <p>How do a recieve the value of op1 times 1,000 instead of having it repeated 1,000 times? When I use the float() argument I get </p>
  
  <pre><code>Traceback (most recent call last):
    File "&lt;stdin&gt;", line 5, in &lt;module&gt;
  TypeError: float() argument must be a string or a number
  </code></pre>
