title: Input html form data from python script
body: <p>I am working on a project and I need to validate a piece of data using a third party site. I wrote a python script using the lxml package that successfully checks if a specific piece of data is valid. </p>
  
  <p>Unfortunately, the site does not have a convenient url scheme for their data and therefor I can not predict the specific url that will contain the data for each unique request. Instead the third party site has a query page with a standard html text input that redirects to the proper url.</p>
  
  <p>My question is this: is there a way to input a value into the html input and submit it all from my python script?</p>
