I read 'some' introductions into Python Regexes
and got confused in the first place when to use
what and why.
After some minutes in this NG I start to get
the picture. So I narrowed the above regex-question
down to a nice equivalence between Perl and Python:
Python:
import re
t = 'blue socks and red shoes'
if re.match('blue|white|red', t):
print t
t = 'blue socks and red shoes'
if re.search('blue|white|red', t):
print t
Perl:
use Acme::Pythonic;
$t = 'blue socks and red shoes'
if $t =~ /blue|white|red/:
print $t
And Python Regexes eventually lost (for me) some of
their (what I believed) 'clunky appearance' ;-)
Thanks
