将python文件上传到Google App Engine

Question

每当我将一个python文件上传到除main.py之外的Google App Engine时，我在尝试加载网站时出现404错误。例如，当我在yaml中包含test.py部分时，我在整个站点上收到404错误。这是我的yaml

    application: pythontest
version: 1
runtime: python
api_version: 1
threadsafe: true

handlers:
- url: /(.*\.(gif|png|jpg|ico|js|css))
  static_files: \1
  upload: (.*\.(gif|png|jpg|ico|js|css))


- url: /python/test.py
  static_files: test.py  

- url: .*
  script: main.py

我的main.py

import os
from google.appengine.ext import webapp
from google.appengine.ext.webapp import util
from google.appengine.ext.webapp import template

class MainHandler(webapp.RequestHandler):
  def get (self, q):
    if q is None:
      q = 'index.html'

    path = os.path.join (os.path.dirname (__file__), q)
    self.response.headers ['Content-Type'] = 'text/html'
    self.response.out.write (template.render (path, {}))

def main ():
  application = webapp.WSGIApplication ([('/(.*html)?', MainHandler)], debug=True)
  util.run_wsgi_app (application)

if __name__ == '__main__':
  main ()

导致这种情况发生的原因是什么？
