Now, we pass the methodPerson.printAgeas an argument to the functionclassmethod. This converts the method to a class method so that it accepts the first parameter as a class (i.e. Person). In the final line, we callprintAgewithout creating a Person object like we do for static methods....

we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...
class A(object): def __call__(self): print 'Hello Python' 那么a= A() a() 会输出'Hello Python' ;可以认为 PyA_Type 对象的 tp_call 不为空。在 c++ 看来也就是函数对象的实现。 所谓“调用”,就是执行对象的 type 所对应的 class 对象的 tp_call 操作。

同样,我们也可以先动态创建一个class,然后再赋给其新的方法: >>> child_example= type('child_example',(class_example,),{})>>>defanother_method(self):... print('another method')...>>> child_example.another_method= another_method>>> hasattr(child_example,'another_method')True>>> child_ex...
