Access static variable from static method
I want to access a static variable from a static method:
#!/usr/bin/env python
class Messenger:
name = "world"
@staticmethod
def get_msg(grrrr):
return "hello " + grrrr.name
print Messenger.get_msg(Messenger)
How to do it without passing grrrr to a method? Is this the true OOP?..
Anything like name or self.name seems not working:
NameError: global name 'name' is not defined
and
NameError: global name 'self' is not defined
Use @classmethod instead of @staticmethod . Found it just after writing the question.
In many languages (C++, Java etc.) "static" and "class" methods are synonyms. Not in Python.
def get_msg():
return "hello " + Messenger.name
You can't use self.name because self is not defined. self is a naming convention for the first parameter of non-static or non-classmethod methods. It points to the object on which you called the method. Since you're method is static, you don't need an object to call it on.
