Static method is similar to a class method, which can be accessed without an object. A static method is accessible to every object of a class, but methods defined in an instance are only able to be accessed by that object of a class. Static methods are not allowed to access the state ...
static method static method不与类中的任何元素绑定。static method就如同在python文件中直接定义一个方法一样,不同之处只在于。同class method和instance method不同的是,static method不接收任何隐式传入的参数(比如class method的cls和instance method的self)。static method可以由类本身或类实例调用。 staticmethod所...
这又离不开描述器了,在上面的代码当中我们使用staticmethod装饰函数my_static_method然后在类MyClass当中会有一个类 staticmethod 的对象,且名字为 my_static_method 。我们需要注意到的是上面的过程用一行代码表示为my_static_method = staticmethod(my_static_method),传入的 my_static_method 就是 my_static_method...

print(A.class_foo) #<bound method A.class_foo of <class '__main__.A'>> print(a.static_foo) #<function A.static_foo at 0x0E2A4F60> print(A.static_foo) #<function A.static_foo at 0x0E2A4F60> foo expects 2 arguments, while a.foo only expects 1 argument. a is bound to foo...

<class '__main__.MethodTest'> this is static method Process finished with exit code 0 1. 2. 3. 4. 5. 6. 7. class MethodTest(object): def __init__(self, input_string): self.my_string = input_string def normalMethod(self): ...
本文简单介绍了Python类中的静态方法与类方法,及两者间的区别。静态方法 静态方法是类中的函数,不需要实例(类似于C++中的静态成员函数)。静态方法主要是用来存放逻辑性的代码,主要是一些逻辑属于类,但是和类本身没有交互,即在静态方法中,不会涉及到类中的方法和属性的操作。 类方法 类方法是将类本身作为对象进行操...
Static method What about staticmethod? It's pretty similar to classmethod but doesn't take any obligatory parameters (like a class method or instance method does). Let's look at the next use case. We have a date string that we want to validate somehow. This task is also logically bound ...
