First off you should have spaces between the name and the operator in the
query string.
However that won't solve you problem in this case in the code of
datastore.Query you will see the following docs
> query = Query('Person')
> query.update({'name =': 'Ryan', 'age >=': 21})
The supported operators are =, >, <, >=, and <=. Only one inequality
filter may be used per query. Any number of equals filters may be used in
a single Query.
With a bit of further digging in appengine.datastore.datastore_query you
can see the set of _INEQUALITY_OPERATORS and != is not one of them
So you will need to rethink what you are doing.
