title: selenium iterate through options in dropdown select
body: <p>I'm using selenium in python, and I have a dropdown that I'm trying to select from. Essentially, I just want to iterate through all the options, like so:</p>
  
  <pre><code>select first option 
    submit page 
    \\ do stuff
  select second option 
    submit page 
    \\ do stuff
  select third option 
    submit page 
    \\ do stuff
  etc...
  </code></pre>
  
  <p>I know it's possible to do this if you know what each of the option values are (you just create a list of those values), but is there a way of just iterating through all the options when you don't know what the option values are?</p>
  
  <p>Thanks! </p>
