Dear Friends,

Can you please provide me a very simple HELLO WORLD type python script
using Template System ?

Actually, whatever example i find in the internet or google forum, is
either too big and complex or not working at all.

Please help me out.

An example like the one in the Getting started guide?

How about this:
(assumes you have the "helloworld.html" stored in the "templates"
subfolder of where your code is)


*****for 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):
template_values = { 'textMessage': 'Hello World', }
path = os.path.join(os.path.dirname(__file__), 'templates/
helloworld.html')
self.response.out.write(template.render(path, template_values))

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

if __name__ == '__main__':
main()



****for helloworld.html:


<html>
<head>
<title>My Template</title>
</head>

<body>
<p> {{textMessage}} </p>
</body>
</html>

Oops!

Of course the code under "def get(self):" should be indented
accordingly.

You should probably use some other template system (e.g. django.template), as webapp.template is going to be deprecated soon.
