Extended 'namedtuple' by default values.
Project description
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.
