The information that has been returned is not complete until the channel.get_pty () was added.

The official documentation describes this:
get_pty(*args, **kwds)

Request a pseudo-terminal from the server. This is usually used-creating a client channel, to ask the server to provide some basic terminal semantics for A shell invoked with invoke_shell . It isn ' t necessary (or desirable) to the call of this method if you ' re going to exectue a single command with exec_command .
