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)
