POST method in Google App Engine

I have an html file named index.html, in which I have a header reference to javascript file(graph.js). There is a submit button on my html page. Method attribute of my form is post.

There is a list named adj_list in my graph.js. How can I get the adj_list in my python class's post method? (I don't know how to pass adj_list with url.something like below..)

<form name="graph" action="/sign?.."开发者_开发技巧 method="post">

The appengine docs include getting started guides for both java and python. The tutorial shows how to handle a request form.
