Thanks, Nick. When I first came across this issue, I thought that dataclasses would take care of what you wrote below, but after looking at the original discussion on python-dev, I thought the problem was ordering None within a comparison with None being a valid value in SQLite. For example, >>> a = [1, None, 'a'] >>> b = [1, 5, 'b'] >>> a == b False >>> a < b Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: '<' not supported between instances of 'NoneType' and 'int'

Thanks, Nick.

For example,
>>> a = [1, None, 'a']
>>> b = [1, 5, 'b']
>>> a == b
False
>>> a < b
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: '<' not supported between instances of 'NoneType' and 'int'
