html - Using webapp2, how can I get the value of a form's "name" attribute during a POST request?

Question

Code:

<form role="form" name="upload_type" action="/upload" method="POST" enctype="multipart/form-data"> 

I would like to inform my application to what type of form is being submitted by a user. I thought I could use the form's "name" attribute but can not figure out how to retrieve this value using webapp2.
