They certainly are. Any time you assign a lambda function directly to
a simple name, it's probably worth replacing with a def function:
def value_factory(_, row):
"""Row factory. To be used with single-column queries."""
return row[0]
(Though I'd be inclined to give the first parameter a proper name here)
