I'm in the process of upgrading our app to use Python 3. Specifically I'm using Python 3.6.2. While making this upgrade I started getting this error (AttributeError: module 'symbol' has no attribute 'list_for') when running the following line of code:
items = items.filter('i.id in [2]')Is there a different way I should be writing this query to work with Python 3? I need to use the string query format so that I can build the query as a part of our api.
