The python pip package installs a "meshtastic" command line executable, which displays packets sent over the network as JSON and lets you see serial debugging information from the meshtastic devices. This command is not run inside of python, you run it from your operating system shell prompt directly. If when you type "meshtastic" it doesn't find the command and you are using Windows: Check that the python "scripts" directory is in your path.
