[Tutor] Regexes -- \b ; re.sub

[John Abbe]

Can someone explain to me why this...

import re
matches = re.search (re.compile ("(.)\b(.)"), "spam and eggs are yummy")
if matches:
    print matches.groups()
else:
    print "no match"

...prints out "no match", and this...

print re.sub (re.compile ("(i)"), "o\1o", "i like eggs and spam")

...prints out "oo looke eggs and spam" -- shouldn't it be "oio loioke 
eggs and spam", after all this...

print re.search (re.compile ("(i)"), "i like eggs and spam").group(1)

...prints out "i"

Mucho thanks...Life,
John
