How to use: Python Code Collection Code class A (object): Def foo (self,x): #类实例方法 print "executing foo (%s,%s)"% (self,x) @classmethod def class_foo (cls,x): #类方法 print "executing class_foo (%s,%s)"% (cls,x) @staticmetho D def static_foo (x): #静态方法 print "executing static_foo (%s)"%x
Call method: Python code collection Code A = A () A.foo (1)//print:executing foo (<__main__. A object at 0xb77d67ec>,1) A.class_foo (1)//executing Class_foo (<class ' __main__. A ' >,1) A.class_foo (1)//executing Class_foo (<class ' __main__. A ' >,1) A.static_foo (1)//executing Static_foo (1) a.static_foo (1)//executing Static_foo (1)
The difference: Both class and static methods can be called by class and class instances, and class instance methods can only be called by class instances where the implied invocation parameters of a class method are classes, whereas the implied invocation parameters of a class instance method are instances of the class, and static methods do not implicitly invoke parameters
