Regular expressions in Python by example

Every time I come back to Python from the land of Perl here at work, I need to re-learn how to use regular expressions in Python, as it is, IMHO, quite a bit different from Perl.

Rather than trawling through the docs again, I made some online notes this time.

Hope it is useful to somebody.
