如何用Python开发CMS系统的数据存储管理功能

import mysql.connector

# 连接数据库
mydb = mysql.connector.connect(
   host="localhost",
   user="yourusername",
   password="yourpassword",
   database="yourdatabase"
)

# 创建数据库表
mycursor = mydb.cursor()
mycursor.execute("CREATE TABLE customers (id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255), email VARCHAR(255))")

# 插入数据
sql = "INSERT INTO customers (name, email) VALUES (%s, %s)"
val = ("John", "john@example.com")
mycursor.execute(sql, val)
mydb.commit()

# 删除数据
sql = "DELETE FROM customers WHERE name = 'John'"
mycursor.execute(sql)
mydb.commit()

# 更新数据
sql = "UPDATE customers SET name = 'Peter' WHERE name = 'John'"
mycursor.execute(sql)
mydb.commit()

# 查询数据
mycursor.execute("SELECT * FROM customers")
myresult = mycursor.fetchall()

for x in myresult:
   print(x)

import mysql.connector

# 连接数据库
mydb = mysql.connector.connect(
   host="localhost",
   user="yourusername",
   password="yourpassword",
   database="yourdatabase"
)

# 创建文章表
mycursor = mydb.cursor()
mycursor.execute("CREATE TABLE articles (id INT AUTO_INCREMENT PRIMARY KEY, title VARCHAR(255), content TEXT)")

# 添加文章
def add_article(title, content):
   sql = "INSERT INTO articles (title, content) VALUES (%s, %s)"
   val = (title, content)
   mycursor.execute(sql, val)
   mydb.commit()

# 删除文章
def delete_article(article_id):
   sql = "DELETE FROM articles WHERE id = %s"
   val = (article_id,)
   mycursor.execute(sql, val)
   mydb.commit()

# 更新文章
def update_article(article_id, title, content):
   sql = "UPDATE articles SET title = %s, content = %s WHERE id = %s"
   val = (title, content, article_id)
   mycursor.execute(sql, val)
   mydb.commit()

# 查询文章
def get_article(article_id):
   sql = "SELECT * FROM articles WHERE id = %s"
   val = (article_id,)
   mycursor.execute(sql, val)
   result = mycursor.fetchone()
   return result

# 使用示例
add_article("Python开发CMS系统", "CMS系统是用于建设和管理网站的一种工具。Python提供了丰富的工具，可以快速开发CMS系统。")
article_id = 1
delete_article(article_id)
title = "Python开发CMS系统实战"
content = "本文介绍如何用Python开发CMS系统的数据存储管理功能。"
update_article(article_id, title, content)
result = get_article(article_id)
print(result)
