Titlecasing a string with exceptions

Answer 1

There are these methods:

>>> mytext = u'i am a foobar bazbar'
>>> print mytext.capitalize()
I am a foobar bazbar
>>> print mytext.title()
I Am A Foobar Bazbar

There's no lowercase article option. You'd have to code that yourself, probably by using a list of articles you want to lower.
