[BangPypers] How to convert Datastore data into a CSV file python

[HUSSAIN BOHRA]

I think with datastore, you meant to say 'Google App Engine Datastore'... ?
If this is the case, please read API details available at:
https://developers.google.com/appengine/docs/python/datastore/

This would help you extracting data out of datastore.

Thanks,
