Hi,
I was wondering if there was a shorthand way to get a reference to a
method object from within that method's code.
Take this code snippet as an example:
import re
class MyClass(object):
def find_line(self, lines):
if not hasattr(MyClass.do_work, "matcher"):
MyClass.do_work.matcher = re.compile("\d - (.+)")
for line in lines:
m = MyClass.do_work.matcher.match(line)
if m:
return m.groups()
Here, I have a method which uses a regular expression object to find
matches. I want the regexp object to be tied to the function, but I
don't want to have to recreate it every time the function is called
Just an idea:
------------------------------
import re
def matches(patt):
def wrapper(fn):
def inner(self, *args, **kw):
return fn(self, *args, **kw)
inner.match = re.compile(patt).match
return inner
return wrapper
class MyClass(object):
@matches('ab(.*)')
def func(self):
print 'hi'
return 5
c = MyClass()
ret = c.func()
print ret
print c.func.match('abc').groups()
------------------------------------
