Extracting URLs from what?

If it is HTML, then I'd look at some existing HTML parsing modules like
Beautiful Soup and Barnes' HTMLData.

Google turns this up:

But I've seen other re's for this problem that are hundreds of
characters long.

These are the regexps that gnome-terminal uses for it's URL
auto-recognition, and I have shamelessly stolen them for use in one of
my own apps:

urlfinders = [
re.compile("([0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}|(((news|telnet|nttp|file|http|ftp|https)://)|(www|ftp)[-A-Za-z0-9]*\\.)[-A-Za-z0-9\\.]+)[0-9]*)?/[-A-Za-z0-9_\\$\\.\\+\\!\\*\\(\\),;&=\\?/~\\#\\%]*[^]'\\.}>\\),\\\"]"),
re.compile("([0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}|(((news|telnet|nttp|file|http|ftp|https)://)|(www|ftp)[-A-Za-z0-9]*\\.)[-A-Za-z0-9\\.]+)[0-9]*)?"),
re.compile("(~/|/|\\./)([-A-Za-z0-9_\\$\\.\\+\\!\\*\\(\\),;&=\\?/~\\#\\%]|\\\\
)+"),
re.compile("'\\<((mailto|)[-A-Za-z0-9\\.]+@[-A-Za-z0-9\\.]+"),
]
