Special Methods Table
---------------------
This table lists all of the special methods together with their parameter and
return types. In the table below, a parameter name of self is used to indicate
that the parameter has the type that the method belongs to. Other parameters
with no type specified in the table are generic Python objects.
You don't have to declare your method as taking these parameter types. If you
declare different types, conversions will be performed as necessary.
You can find an updated version of the special methods table
in :ref:`special_methods_table`.
