This is interesting.
What's in this example the difference then between:
import re
t = 'blue socks and red shoes'
if re.compile('blue|white|red').match(t):
print t
and
t = 'blue socks and red shoes'
if re.search('blue|white|red', t):
print t

Thats true. Thank you for pointing this out.
But what would be an appropriate use
of search() vs. match()? When to use what?
I answered the posting in the first place
because also I'm coming from a C/C++/Perl
background and trying to get along in Python.
Thanks,
