access is denied in GAE in eclipse

Question

When I am trying to to do Model.put() in eclipse for a google python app after changing the parameter of --datastore_path="F:/tmp/myapp_datastore" in arguments of debug configurations.I dont know if its related to above change or is there any other magic behind the scene. Any help.

exception value:[Error 5] Access is denied 

UPDATE, Added codes for OP,

Everything is working fine for another application from command prompt but when i use the same from eclipse i get following dump

The below comes in console window of eclipse

Answer 1

According to this error,

TypeError: 'str' object is not callable 

I guess, you have shadowed built-in object str to something else.

For example, you used str="dummy" in your code and str became uncallable object.
