Question

I’m lazy! And I just want to store one single string value. That’s all!
Can I jump over any kind of Modeling and just store a value?

Depending on how long you want to store the information, you can also use memcache:

Import:

from google.appengine.api import memcache

All you need to know to get and set data:

memcache.set("key", value)
value = memcache.get("key")

If your data needs long-term persistance, then you need to use the backend datastore. It is recommended to use both memcache and the datastore for your data, since the memcache can be flushed at any time. For short-term, ephemeral persistance, memcache does the trick.
