"""Register an update handler.
|
||
|
|
|
||
|
|
You can register multiple handlers, but at most one handler within a group will be used for a single update.
|
||
|
|
To handle the same update more than once, register your handler using a different group id (lower group id
|
||
|
|
== higher priority). This mechanism is explained in greater details at
|
||
|
|
:doc:`More on Updates <../../topics/more-on-updates>`.
|
||
|
|
|
||
|
|
Parameters:
|
||
|
|
handler (``Handler``):
|
||
|
|
The handler to be registered.
|
||
|
|
|
||
|
|
group (``int``, *optional*):
|
||
|
|
The group identifier, defaults to 0.
|
||
|
|
|
||
|
|
Returns:
|
||
|
|
``tuple``: A tuple consisting of *(handler, group)*.
