Search for brackets in a case insensitive using regular expressions

Question

with open(logfile) as inf:
    for line in inf:
        if re.search(string,line,re.IGNORECASE):
            print 'found line',line

So how to search string contains brackets,- characters using Python

Answer 1

import re

s = "foo[bar]baz"
m = re.search("[\[\]]", s)
print m.group(0)
# => '['

t = "foo-bar]baz"
n = re.search("[\[\]]", t)
print n.group(0)
# => ']'

In fact, re.IGNORECASE is unnecessary since bracktes have no case.

Edit:

u = "foo\\-bar]baz"
o = re.search('[\[\]]', u) # Does this match the \ ?
print o.group(0)
# => ']'
# Behold!
