Python Classmethod modifier

The function that corresponds to the classmethod modifier does not need to be instantiated and does not require the self parameter , but the first parameter needs to be a cls parameter that represents its own class, which can be used to invoke the properties of the class , the methods of the class , the instantiation of objects , and so on. Returns the class method.

Instance:

1 #!/usr/bin/python2 #-*-coding:utf-8-*-3  4 classA (object):5Bar = 16     deffunc1 (self):7         Print 'Foo'  8 @classmethod9     defFunc2 (CLS):Ten         Print 'Func2' One         PrintCls.bar ACLS (). FUNC1 ()#Call the Foo method -   -A.FUNC2 ()#No instantiation required

Output:

1 Func2 2 13 foo
