[Tutor] Regular expression oddity

[Emmanuel Ruellan]

Hi tutors!

While trying to write a regular expression that would split a string
the way I want, I noticed a behaviour I didn't expect.

>>> re.findall('.?', 'some text')
['s', 'o', 'm', 'e', ' ', 't', 'e', 'x', 't', '']

Where does the last string, the empty one, come from?
I find this behaviour rather annoying: I'm getting one group too many.

Regards,
Emmanuel
