uploading file

[Nasser Abdou]

Hi!

Please i'm using webapp2 on google app engine

I encountered a problem

Sorry my english is not good

I'm working about an application where user can upoad a file and then the application analysis it

For exemple, the file is a sequence of DNA

The application will count the number of nucleotids

How can i do?

this is my code:

import webapp2

import cgi

class BioAnalyse(webapp2.RequestHandler):

    def get(self):

        self.response.write("""<div id="contenu">

    <form action="/" method="post" enctype="multipart/form-data">

    <input type="file" name="fichier"/>

    <input type="submit" value="Lancez l'analyse"/>

    </form>

    </div>"""

    def post(self):

        file = cgi.FieldStorage()

        fileitem = file["fichier"]

        # what can i do for open this file

        # and analyse it?
