This method takes the class itself as an argument and we can use it to access or modify static class variables. You can use the class method to define a static class variable which you can access using the class
class class_name: static_variable_1 = value static_variable_2 = value ... ... # Class methods definitions ... ... Accessing static variablesStatic variables can be accessed with the class name without creating its instance, they can also be accessed with the instance name if you created ...
Note python has this really weird error if you define local variable in a function same name as the global variable, program will promptUnboundLocalError. child class object overrides parent class methods input: classfruit:defprint(self):print('a')defeat(self):print('b')classapple(fruit):defpr...
So, as we can see from usage of staticmethod, we don’t have any access to what the class is- it’s basically just a function, called syntactically like a method, but without access to the object and it’s internals (fields and another methods), while classmethod does. 所以,从静态方法...
@staticmethod means: when this method is called, we don't pass an instance of the class to it (as we normally do with methods). This means you can put a function inside a class but you can't access the instance of that class (this is useful when your method does not use the insta...

After importing the socket module, we instantiate a new variable s from the class socket class. Next, we use the connect() method to make a network connection to the IP address and port. Once successfully connected, we can read and write from the socket. The recv(1024) method will read...
