This article mainly explains "how to implement the command mode in Python". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to implement command mode in Python".

The first is the Receiver class:

This class is only the Operand of the command instance and is not a necessary part of the command mode. Its function is simple: after a simple addition, the result is indented and output as specified by prefix.

The concrete command class is used to define the actual action of the execute. In the above example, the execute method calls the action method of receiver. In actual development, multiple representational classes can be defined, each of which can call different methods for different (type or instance) receiver.

Invoker is the actual action caller. It performs the actions of the Command as needed and does not care about the actual content of the Command.

Next is an example of using command mode.

Through the nested structure of the output, it is easier to understand the execution of the two Command.

At this point, I believe you have a deeper understanding of "how to achieve command mode in Python". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
