I have a sample code as bellow:
#!/usr/bin/env python
class Hello:
def __init__(self):
print "Hello __init__"
@classmethod
def print_hello(self):
print "hello"
Hello.print_hello()
If I move "self" parameter of print_hello away, this code fragment won't
work.
I am wondering when Hello.print_hello() executes, what value will "self"
be asigned?
The self variable above with be populated with a reference to the class,
so it would be more appropriately named cls such as:
@classmethod
def print_hello(cls):
print "hello"
But you might consider decorating the method as a static method instead
since in your example you are not using the parameter at all. A static
method would not require a parameter.
@staticmethod
def print_hello():
print "hello"
