mapping a string to an instancemethod

[mh@pixar.com]

The following bit of code will allow an instance member to
be called by reference. How can I map a string (e.g.
"hello1" or "Foo.hello1 " to a the instance member?

class Foo:
def hello1(self, p):
print 'hello1', p
def hello2(self, p):
print 'hello2', p
def dispatch(self, func, p):
func(self,p)

f=Foo()
f.dispatch(Foo. hello1, 23)
f.dispatch(Foo. hello1, 24)

f.dispatch_as_s tring("hello1", 23) ## this is what I want to do.

Many TIA and apologies if this is a FAQ, I googled and couldn't
find the answer.

Do what's below. Then learn about *args to make a version that
works with variable numbers of parameters...

class Foo:
def hello1(self, p):
print 'hello1', p
def hello2(self, p):
print 'hello2', p
def dispatch(self, func, p):
func(self,p)
def dispatch_as_str ing(self, funcname, p):
getattr(self, funcname)(p)

f = Foo()
f.dispatch_as_s tring('hello1', 'world')

Many TIA and apologies if this is a FAQ, I googled and couldn't
find the answer.
