New submission from poornaprudhvi <poornagur...@gmail.com>:
>>> from collections import namedtuple
>>> sample = namedtuple('Name','a','b','c')
This is returning the following code as output:
class Name(tuple):
'Name(a,)'
__slots__ = ()
_fields = ('a',)
def __new__(_cls, a,):
'Create new instance of Name(a,)'
return _tuple.__new__(_cls, (a,))
@classmethod
def _make(cls, iterable, new=tuple.__new__, len=len):
'Make a new Name object from a sequence or iterable'
result = new(cls, iterable)
if len(result) != 1:
raise TypeError('Expected 1 arguments, got %d' % len(result))
return result
def __repr__(self):
'Return a nicely formatted representation string'
return 'Name(a=%r)' % self
def _asdict(self):
'Return a new OrderedDict which maps field names to their values'
return OrderedDict(zip(self._fields, self))
def _replace(_self, **kwds):
'Return a new Name object replacing specified fields with new values'
result = _self._make(map(kwds.pop, ('a',), _self))
if kwds:
raise ValueError('Got unexpected field names: %r' % kwds.keys())
return result
def __getnewargs__(self):
'Return self as a plain tuple. Used by copy and pickle.'
return tuple(self)
__dict__ = _property(_asdict)
def __getstate__(self):
'Exclude the OrderedDict from pickling'
pass
a = _property(_itemgetter(0), doc='Alias for field number 0')
