I
love the
(?P<foo>) named regexp groups in Python. They make the
code so much more readable! But are they slower? Not much.
timeit.py -r 50
The named groups version is about 6% slower. Consistent, but not very
significant.
-s 'import re; r = re.compile("foo (?P<x>bar)")' 'm = r.match("foo bar"); g = m.group("x")' 100000 loops, best of 50: 3.34 usec per loop timeit.py -r 50 -s 'import re; r = re.compile("foo (bar)")' 'm = r.match("foo bar"); g = m.group(1)' 100000 loops, best of 50: 3.14 usec per loop |
