How to use MySQL and Python to develop a simple online music platform

With the rapid development of the Internet, music platforms have become indispensable in many people’s entertainment lives part. This article will introduce how to use MySQL and Python to develop a simple online music platform.

1. Preparation

First, we need to install MySQL and Python on the computer. MySQL is a commonly used relational database management system, and Python is a simple and easy-to-use programming language.

Install MySQL:

1. Go to the MySQL official website to download the installation package.
2. Double-click the installation package and follow the prompts to install.
3. During the installation process, remember the MySQL username and password, which will be used later.

Install Python:

1. Go to the official Python website to download the installation package.
2. Double-click the installation package and follow the prompts to install.

2. Create a database

Open MySQL and log in using the username and password set previously. Create a new database to store data related to music platforms.

Sample code:

CREATE DATABASE music_platform;

3. Create a data table

Create a data table in the database to store related information such as songs, artists, and users.

Sample code:

USE music_platform;

CREATE TABLE songs (
    id INT PRIMARY KEY AUTO_INCREMENT,
    title VARCHAR(100),
    artist VARCHAR(100),
    duration INT
);

CREATE TABLE artists (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(100),
    genre VARCHAR(50)
);

CREATE TABLE users (
    id INT PRIMARY KEY AUTO_INCREMENT,
    username VARCHAR(50),
    password VARCHAR(50)
);

4. Connect to the database

Use the pymysql library in Python to connect to the MySQL database and establish the corresponding table structure.

Sample code:

import pymysql

# 连接到MySQL数据库
conn = pymysql.connect(
    host='localhost',  # MySQL主机名
    user='your_username',  # MySQL用户名
    password='your_password',  # MySQL密码
    database='music_platform'  # 数据库名
)

# 创建数据表
def create_tables():
    cursor = conn.cursor()
    cursor.execute('''
        CREATE TABLE IF NOT EXISTS songs (
            id INT PRIMARY KEY AUTO_INCREMENT,
            title VARCHAR(100),
            artist VARCHAR(100),
            duration INT
        );
    ''')
    cursor.execute('''
        CREATE TABLE IF NOT EXISTS artists (
            id INT PRIMARY KEY AUTO_INCREMENT,
            name VARCHAR(100),
            genre VARCHAR(50)
        );
    ''')
    cursor.execute('''
        CREATE TABLE IF NOT EXISTS users (
            id INT PRIMARY KEY AUTO_INCREMENT,
            username VARCHAR(50),
            password VARCHAR(50)
        );
    ''')
    conn.commit()

# 关闭数据库连接
def close_connection():
    conn.close()

5. Operation database

After creating the database and data table, we can add, delete, modify and query data through Python code.

1. Add song:

   def add_song(title, artist, duration):
    cursor = conn.cursor()
    cursor.execute('INSERT INTO songs (title, artist, duration) VALUES (%s, %s, %s)', (title, artist, duration))
    conn.commit()

2. Add artist:

   def add_artist(name, genre):
    cursor = conn.cursor()
    cursor.execute('INSERT INTO artists (name, genre) VALUES (%s, %s)', (name, genre))
    conn.commit()

3. Add user:

   def add_user(username, password):
    cursor = conn.cursor()
    cursor.execute('INSERT INTO users (username, password) VALUES (%s, %s)', (username, password))
    conn.commit()

4. Query song:

   def search_songs(title):
    cursor = conn.cursor()
    cursor.execute('SELECT * FROM songs WHERE title = %s', (title,))
    return cursor.fetchall()

5. Query artist:

   def search_artists(name):
    cursor = conn.cursor()
    cursor.execute('SELECT * FROM artists WHERE name = %s', (name,))
    return cursor.fetchall()

6. Query user:

   def search_users(username):
    cursor = conn.cursor()
    cursor.execute('SELECT * FROM users WHERE username = %s', (username,))
    return cursor.fetchall()

   The above is only a sample code. In actual development, it needs to be optimized and improved according to business needs.

   6. Summary

   This article introduces how to use MySQL and Python to develop a simple online music platform. By creating databases and data tables, and using Python code to operate the database, we have implemented the functions of adding, deleting, modifying, and querying data such as songs, artists, and users. Of course, in the actual development process, the code needs to be further optimized and improved to make the music platform more complete and stable. I hope this article can help you develop a music platform.
