How to retrieve google appengine entities using their numerical id?

Is it possible to retrieve an entity from google appengine using their numerical IDs and if so how? I tried using:

key = Key.from_path("ModelName", numericalId) m = ModelName.get(key)

but the key generated wasnt correct.

From stackoverflow

• Getting an Entity Using a Key

• Turns out I needed to do

  key = Key.from_path( Application_ModelName, numeric_id )

  wasn't clear till i looked at the dict() of an entity
