title: how to pass textarea value as parameter of url request in python
body: <p>this question may have been discussed somewhere else already but just want to get some refreshment from here:
  I have a list (sourse.csv) with bunch of records that all have 3 fields like: ID, Name1, Name2
  I need to look up them in a website abcde.com to validate them
  ID and Name1 correspond to two textboxes on the web page while Name2 is for a textarea</p>
  
  <p>There is a Submit button on the page</p>
  
  <p>Once my python code parses the validation result, I need to write it into a local file (result.csv).</p>
  
  <p>Can anyone enlighten me on how to write the script? especially how to mock up the httprequest with parameters for the textboxes and textarea?</p>
  
  <p>Thank you very much.</p>
