Is the following code is ok. who to call all method.
It is working but the call to m() without a reference to self seems
strange
Ok, so you already know it works - and you want to know why!
class CustomMethod:
def method1(self):
....
def method2(self):
....
def method3(self):
....
def getAllMethod(self):
return [self.method1, self.method2, self.method3]
def applyAll(self):
for m in self.getAllMethod():
# how to call all methods ?
# is it correct
m()
When you write self.method1, you get a "bound method" - it already knows
the instance on which it is called (self, in this case).
When you write CustomMethod.method1, you get an "unbound method" - it is
not bound to any particular instance; you must provide the instance
yourself when calling it.
See "User-defined methods" in http://docs.python.org/ref/types.html - if
you really want to know how this works, read about new-style classes and
the descriptor protocol at http://www.python.org/doc/newstyle/
