 You have to stop here and go back and read the introductory document on appengine and dragon runtime. If you read through the introduction documents, you will see the section on Dragon Runtime and Sandbox and its restrictions. / P> 
 On examining that section of the document, you will see that you have phyllosis in epinegon You can not write the system, but also when you keep other restrictions in mind.  
 Where the code is your error, you should include at least one stacktrace and the special lines of code You should see where the error occurs and instead of asking specific questions about it, all the dumps is saying more about your code than what you got.  
 At the moment I see the problem of your code There are not many points where there is a  is_key  error, the error is the self explanation, the ore and whatever else you are trying to do will not work anyway.
