            _NamedTuple
Known Subclasses:

(INTERNAL) Base for named tuples with both index and attribute name access to the items.

Note: This class is similar to Python's namedtuple, but statically defined, lighter and limited.

Method Details

__delattr__ (self, name)

 

Delete an attribute by name.

Overrides: object.__delattr__

Note: Items can not be deleted.

__hash__ (self)
(Hashing function)

 

hash(x)

Overrides: object.__hash__
(inherited documentation)

__new__ (cls, arg, *args, **iteration_name)
Static Method

 

New _NamedTuple initialized with positional arguments.

Arguments:
  • arg - Tuple items (tuple, list, ...) or first tuple item of several more in other positional arguments.
  • args - Tuple items (any), all positional arguments.
  • iteration_name - Only keyword arguments iteration=None and name=NN are used, any other are silently ignored.
Returns: a new object with type S, a subtype of T
Raises:
  • LenError - Unequal number of positional arguments and number of item _Names_ or _Units_.
  • TypeError - The _Names_ or _Units_ attribute is not a tuple of at least 2 items.
  • ValueError - Item name is not a str or valid identifier or starts with underscore.
Overrides: object.__new__

__repr__ (self)
(Representation operator)

 

Default repr(self).

Overrides: object.__repr__

__setattr__ (self, name, value)

 

Set attribute or item name to value.

Overrides: object.__setattr__

__str__ (self)
(Informal representation operator)

 

Default repr(self).

Overrides: object.__str__

dup (self, name='', **items)

 

Duplicate this tuple replacing one or more items.

Arguments:
  • name - Optional new name (str).
  • items - Items to be replaced (name=value pairs), if any.
Returns:
A copy of this tuple with items.
Raises:
  • NameError - Some items invalid.
Overrides: _Named.dup

items (self)

 

Yield the items, each as a (name, value) pair (2-tuple).

See Also: Method .units.

iteritems (self)

 

Yield the items, each as a (name, value) pair (2-tuple).

See Also: Method .units.

iterunits (self, Error=<class 'pygeodesy.errors.UnitError'>)

 

Yield the items, each as a (name, value) pair (2-tuple) with the value wrapped as an instance of its units class.

Arguments:
  • Error - Error to raise for units issues (UnitError).
Raises:
  • Error - Invalid Named-Tuple item or units class.

See Also: Method .items.

toRepr (self, prec=6, sep=', ', fmt='F', **unused)

 

Return this Named-Tuple items as name=value string(s).

Arguments:
  • prec - The float precision, number of decimal digits (0..9). Trailing zero decimals are stripped for prec values of 1 and above, but kept for negative prec values.
  • sep - Separator to join (str).
  • fmt - Optional float format (letter).
Returns:
Tuple items (str).
Overrides: _Named.toRepr

toStr (self, prec=6, sep=', ', fmt='F', **unused)

 

Return this Named-Tuple items as string(s).

Arguments:
  • prec - The float precision, number of decimal digits (0..9). Trailing zero decimals are stripped for prec values of 1 and above, but kept for negative prec values.
  • sep - Separator to join (str).
  • fmt - Optional float format (letter).
Returns:
Tuple items (str).
Overrides: _Named.toStr

toUnits (self, Error=<class 'pygeodesy.errors.UnitError'>)

 

Return a copy of this Named-Tuple with each item value wrapped as an instance of its units class.

Arguments:
  • Error - Error to raise for units issues (UnitError).
Returns:
A duplicate of this Named-Tuple (Named-Tuple).
Raises:
  • Error - Invalid Named-Tuple item or units class.

units (self, Error=<class 'pygeodesy.errors.UnitError'>)

 

Yield the items, each as a (name, value) pair (2-tuple) with the value wrapped as an instance of its units class.

Arguments:
  • Error - Error to raise for units issues (UnitError).
Raises:
  • Error - Invalid Named-Tuple item or units class.

See Also: Method .items.
