An ode to re.finditer()

[Robert Oschler]

I figured I'd utter some words of praise for re.finditer().  It's such a
great feeling, when you come across a single statement that does everything
you want in two lines of code:

for g in re.finditer(pattern, string):
    do_something_to_g(g)

In two lines of code I can break out all the sub-strings I need with a
regular expressions pattern, and have each of them operated upon by a
function.

Nice.

[Note: Python 2.2.3 or better is needed to use re.finditer()]
