telegram.ext.StringCommandHandler

class telegram.ext.StringCommandHandler(command, callback, pass_args=False, pass_update_queue=False, pass_job_queue=False)

Bases: telegram.ext.handler.Handler

pass_job_queue

Parameters:
  • callback (callable) –

    The callback function for this handler. Will be called when check_update has determined that an update should be processed by this handler. Callback signature for context based API:

    The return value of the callback is usually ignored except for the special case of telegram.ext.ConversationHandler.

  • pass_args (bool, optional) – Determines whether the handler should be passed the arguments passed to the command as a keyword argument called args.

DEPRECATED: Please switch to context based callbacks.
  • pass_job_queue (bool, optional) – If set to True, a keyword argument called job_queue will be passed to the callback function.
