What's the difference between search and findall in [33-34]? And why I
cannot generalize [33] to [35]? Out[35] would make sense to me if I had
put a non-greedy +, but why do re gets only one word?

A string is a sequence of chars, and you can use slices with it [1].

Read this:
In [50]: print str.lstrip.__doc__
S.lstrip([chars]) -> string or unicode
Return a copy of the string S with leading whitespace removed.
If chars is given and not None, remove characters in chars instead.
If chars is unicode, S will be converted to unicode before stripping

Hi!
As a first part of a project, I need to store a directory tree in a mysql db.
I'm wondering if there is a canonical way of doing that. I don't know if it's
an appropriate question for this list, but I think it's not only a choice of
db design, but also a choice of appropriate python tools.
