Is it proper to create a def > main() or just under: if __name__ == "__main__" Either one works; I usually don't put more than a few lines of code in the if block so I would make a main() function. >> then you can build the message as >> body = status.get(event, nomatch) % vars() >> message = header + body + footer > > > That last part I am not so clear on ... how does: body = > status.get(event, nomatch) % vars() work ?
