namedtupledefs2 0.1.20

Extended 'namedtuple' by default values.

The package namedtupledefs2 provides a patched version of the factory class collections.namedtuple with field defaults for namedtuple. The package namedtupledefs2 supports Python2.7 syntax and adds Jython support. This is a drop-in compatible patch with minimal changes only - basically one line in the class template only.

import namedtupledefs

Point0 = namedtupledefs.namedtuple(‘Point’, (‘x’, ‘y’, ‘z’)) Point1 = namedtupledefs.namedtuple(‘Point’, (‘x y z’))

point0 = Point0(11, 22, 33) point1 = Point1(11, 22, 33)

the same with defaults:

from namedtupledefs import namedtuple

Point0defs = namedtupledefs.namedtuple(‘Point’, (‘x’, ‘y’, ‘z’), fielddefaults=(22, 33)) Point1defs = namedtupledefs.namedtuple(‘Point’, (‘x y z’), fielddefaults=(22, 33))

point0defs = Point0defs(11, 22) point1defs = Point1defs(11)

with the identical results:

point0defs == point0 point1defs == point1

of the printout:

>>> point0
Point(x=11, y=22, z=33)

>>> point0defs
Pointdefs(x=11, y=22, z=33)

The package ‘namedtupledefs2’ additionally provides the method _merge for the created class with the accurate handling of _fields and _fielddefaults:

msg_header._merge(‘NewClassName’, msg_body, msg_data)

See doc-string for more examples. For the standard library collections.namedtuple see Python documentation.

For the Python3 syntax refer to namedtupledefs3 or namedtupledefs.
