Question about query equality operator docs

[ckhan]

This page http://code.google.com/appengine/docs/python/datastore/queries.html lists the equality operator as '==' :

The comparison operator can be any of the following:

Operator	Meaning
==	Equal to

But the examples on that page, and the reference for Query.filter http://code.google.com/appengine/docs/python/datastore/queryclass.html#Query_filter use '='

q.filter("last_name =", "Smith")

My experiments seem to indicate that either will work.

Is the table just a typo, or is there a difference?

Hi,
  There should be no difference;  the usage is not even consistent within the SDK code.

  Operator list:

    http://code.google.com/p/googleappengine/source/browse/trunk/python/google/appengine/ext/db/__init__.py#264

  For some example inconsistencies, read over this method:

    http://code.google.com/p/googleappengine/source/browse/trunk/python/google/appengine/ext/db/__init__.py#2422

  They default to '==', yet for the 'in' query '=' is used.
