Hello All,
I have a question about decorators, and I think an illustration would
be helpful. Consider the following simple class:
#begin code
class Foo:
def fooDecorator(f):
print "fooDecorator"
def _f(self, *args, **kw):
return f(self, *args, **kw)
return _f
@fooDecorator
def fooMethod(self):
print "fooMethod"
f = Foo()
f.fooMethod()
#end of code
This code runs, and actually serves my purpose. However, I'm a little
confused about three things and wanted to try and work through them
while I had the time to do so. I believe all of my confusion is related
to the parameters related to the fooDecorator:
-how I would pass arguments into the fooDecorator if I wanted to (my
various attempts have failed)
-what the difference is between decorating with @fooDecorator versus
@fooDecorator()
-why does this code even work, because the first argument to
fooDecorator isn't self
I'm searched the net and read the PEPs that seemed relevant, but I
didn't see much about decorators inside of a class like this. Can
anyone comment on any of these three things?
