如果连接到mysql，如何通过python导入模块？

pip install mysql-connector-python

import mysql.connector

# 创建连接
mydb = mysql.connector.connect(
  host="localhost",  # 数据库主机地址
  user="yourusername",  # 数据库用户名
  password="yourpassword",  # 数据库密码
  database="yourdatabase"  # 要连接的数据库名
)

# 检查连接是否成功
if mydb.is_connected():
    print("Connected to MySQL database")

# 创建cursor对象
mycursor = mydb.cursor()

# 执行SQL查询
mycursor.execute("SELECT * FROM yourtable")

# 获取查询结果
myresult = mycursor.fetchall()

for x in myresult:
  print(x)

mycursor.close()
mydb.close()

try:
    mydb = mysql.connector.connect(
        host="localhost",
        user="yourusername",
        password="yourpassword",
        database="yourdatabase"
    )
    if mydb.is_connected():
        print("Connected to MySQL database")
        mycursor = mydb.cursor()
        mycursor.execute("SELECT * FROM yourtable")
        myresult = mycursor.fetchall()
        for x in myresult:
            print(x)
except mysql.connector.Error as err:
    print(f"Error: {err}")
finally:
    if mydb.is_connected():
        mycursor.close()
        mydb.close()
        print("MySQL connection is closed")
