# the overall pattern/process is that we must use send_interactive as this is an "interactive"
# style command/input because the prompt changes and relies on a human to understand what is
# going on. this whole operation is completed by the `send_interactive` method, but we break it
# up here so its easier to understand what is going on. first we have a "start" point -- where
# we send the actual command that kicks things off -- in this case "banner motd ^" -- we need to
# tell scrapli what to expect so it knows there is success; "Enter TEXT message." in this
# exmaple. We set the "hidden input" to `True` because this forces scrapli to not try to read
# the inputs back off the channel -- we can't read the inputs because they are interrupted by
# the prompt of enter your text blah blah.
banner_start = ("banner motd ^", "Enter TEXT message.", True)
# next we can simply create an "event" for each line of the banner we want to send, we dont
# need to set the "hidden_prompt" value to `True` here because scrapli can simply read the
# inputs off the channel normally as there is no prompts/inputs from the device
banner_lines = [(line, "\n") for line in my_banner.splitlines()]
# then we need to "end" our interactive event and ensure scrapli knows how to find the prompt
# that we'll be left at at the end of this operation. note that you could just capture the
# config mode prompt via `get_prompt` if you wanted and pass that value here, but we'll set it
# manually for this example
