I have no objection to named tuples, but I've sometimes missed having an
equivalent to the Pascal record or C struct: essentially a named mutable
tuple. Here's a quick way to get one:
def record(**kwargs):
"""Lightweight named mutable tuple equivalent."""
class Record(object):
__slots__ = kwargs.keys()
x = Record()
for key, value in kwargs.items():
setattr(x, key, value)
return x
It needs more work to be a full-fledged record, e.g. __eq__ and __str__,
but it's a start.
