I second this advice, but with a slight modification.
If you're using Python 3.3 or higher, it is better to use
message.casefold rather than lower. For English, there's no real
difference:
py> "Hello World!".casefold()
'hello world!'
but it can make a difference for non-English languages:
py> "Große".lower() # German for "great" or "large"
'große'
py> "Große".casefold()
'grosse'
