:param cmd_or_spawn: This can either be an instance of :class:`pexpect.spawn`
in which a REPL has already been started, or a str command to start a new
REPL process.
:param str orig_prompt: The prompt to expect at first.
:param str prompt_change: A command to change the prompt to something more
unique. If this is ``None``, the prompt will not be changed. This will
be formatted with the new and continuation prompts as positional
parameters, so you can use ``{}`` style formatting to insert them into
the command.
:param str new_prompt: The more unique prompt to expect after the change.
:param str extra_init_cmd: Commands to do extra initialisation, such as
disabling pagers.

:param str command: The command to send. Trailing newlines are not needed.
This should be a complete block of input that will trigger execution;
if a continuation prompt is found after sending input, :exc:`ValueError`
will be raised.
:param int timeout: How long to wait for the next prompt. -1 means the
default from the :class:`pexpect.spawn` object (default 30 seconds).
None means to wait indefinitely.
