This is the kind of thing I meant. I think I have to get used to writing
small, light-weight classes. You inspired this variation which is a little
more verbose in the class definition, but less so in the use:
class Matcher:
def search(self, r,s):
self.value = re.search(r,s)
return self.value
def __getitem__(self, i):
return self.value.group(i)
m = Matcher()
if m.search(r'add (\d+) (\d+)', line):
do_add(m[1], m[2])
elif m.search(r'mult (\d+) (\d+)', line):
do_mult(m[1], m[2])
elif m.search(r'help (\w+)', line):
show_help(m[1])
As for using regular expressions too much... they are why I've liked perl so
much for quick file processing for years. I don't like perl objects at all,
which is why I'm trying python, but the re package has not been my favorite
so far...
