from google.appengine.ext.webapp import template

def HtmlRender(self, template_file, template_values):     
temp = os.path.join(os.path.dirname(__file__),
    'templates/'+template_file)
self.response.out.write( template.render(temp, template_values) )


template_values ={
   'url' : self.request.url,
   'my_dictionary' : { 'item1' : 1, 'item2' : 2}
  }

url: {{ url }}
{% for key, value in my_dictionary.items %}
{{ item.key }} : {{ item.value }}
{% endfor %}

As you can see above code. you can app engine template to generate HTML than before generate code from within strings in the Python..

"TemplateSyntaxError: 'for' statements with five words should end in 'reversed': for key, value in my_dictionary.items".

Yes, you will get one error message. What? It looks as normal python code and seems does work. Because Google App Engine now support Django 0.96 version. If you want to receive a dictionary data type from python. You must modify Django template in HTML page.
