在上面的代码中,我们定义了一个名为call_static_method的方法,该方法通过使用类名MyClass来调用静态方法my_static_method。通过创建类的实例,并调用call_static_method方法,将触发静态方法的执行。运行上述代码将输出This is a static method.。 静态方法的用途 静态方法在Python中有许多用途。下面是一些使用静态方法的...

method的原理 static method 静态方法 class method 类方法 abc 抽象方法 什么是方法?他们是怎么运作的?How Methods Work in Python 这里首先要说明的是,方法method和函数function是有区别的,方法method一般存在于我们定义的类class中。但是在Python中,方法method其实就是当成一个class attribute存储的函数function。我们来...

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 ...
