Objects of this type are subscriptable with strings. See :meth:`__getitem__` for more details.
|
|
The :mod:`pickle` and :func:`~copy.deepcopy` behavior of objects of this type are defined by
|
|
:meth:`__getstate__`, :meth:`__setstate__` and :meth:`__deepcopy__`.
|
|
|
|
Tip:
|
|
Objects of this type can be serialized via Python's :mod:`pickle` module and pickled
|
|
objects from one version of PTB are usually loadable in future versions. However, we can
|
|
not guarantee that this compatibility will always be provided. At least a manual one-time
|
|
conversion of the data may be needed on major updates of the library.
|

.. versionchanged:: 20.0
|
|
|
|
* Removed argument and attribute ``bot`` for several subclasses. Use
|
|
:meth:`set_bot` and :meth:`get_bot` instead.
|
|
* Removed the possibility to pass arbitrary keyword arguments for several subclasses.
|
|
* String representations objects of this type was overhauled. See :meth:`__repr__` for
|
|
details. As this class doesn't implement :meth:`object.__str__`, the default
|
|
implementation will be used, which is equivalent to :meth:`__repr__`.
|
|
* Objects of this class (or subclasses) are now immutable. This means that you can't set
|
|
or delete attributes anymore. Moreover, attributes that were formerly of type
|
|
:obj:`list` are now of type :obj:`tuple`.

This method is currently only called in the unpickling process, i.e. not on "normal" init.
|
|
This is because
|
|
* automating this is tricky to get right: It should be called at the *end* of the __init__,
|
|
preferably only once at the end of the __init__ of the last child class. This could be
|
|
done via __init_subclass__, but it's hard to not destroy the signature of __init__ in the
|
|
process.
|
|
* calling it manually in every __init__ is tedious
|
|
* There probably is no use case for it anyway. If you manually initialize a TO subclass,
|
|
then you can pass everything as proper argument.
