Detailed explanation of the introduction and usage of the ‘MyCli’ -ICli class library in Python Overview: MyCli is a Python -based command line interface (CLI) tool, which provides developers with a more friendly and efficient way to interact with the MySQL database.It provides functions such as SQL automatic completion, high grammar, and intuitive data table display, which greatly simplifies the interaction process with the MySQL database. usage: MyCli installation is very simple. You can install it through the PIP command: shell pip install mycli After the installation is completed, you can use the MyCli command to start the CLI interface directly in the command line, and the local MySQL database is connected by default. After starting MyCli, you will prompt the connection information of the MySQL database, including host address, user name, password, etc.After entering the correct connection information, you can start interacting with the database in the CLI interface. Here are some commonly used commands and usage of MyCli: 1. Query data: It is very simple to query the data in MyCli. You only need to enter the SQL statement and press the Enter key.The results will be displayed in the form of a form, which is very intuitive.For example: sql SELECT * FROM users; 2. Insert data: Use the Insert Into statement to insert data into the database table.For example: sql INSERT INTO users (id, name, age) VALUES (1, 'Tom', 20); 3. Update data: Use the update statement to update the data in the database table.For example: sql UPDATE users SET age=21 WHERE name='Tom'; 4. Delete data: Delete the data in the database table with the delete statement.For example: sql DELETE FROM users WHERE age=20; 5. Exit MyCli: Enter the \ q command or press Ctrl+D to exit MyCli. Through configuration files, the use of MyCli can be further customized.By default, MyCli will load the ".myClirc" file located in the user's main catalog as the configuration file.This configuration file is a file in an INI format that can modify the parameters of them to meet personal needs.For example, you can modify the prompt information, set the default database, etc. ini [main] prompt = "mycli> " database = mydb The above is a detailed introduction and usage of the MyCli library.Through MyCli, developers can interact with the MySQL database more efficiently, and enjoy the convenience of SQL automatic completion and high grammar.At the same time, MyCli also provides configuration files, which can be customized according to personal needs.The use of MyCli can greatly improve development efficiency and is one of the indispensable weapons for Python developers.
