pymysql模块没有connect属性

import pymysql

# 连接到MySQL数据库
connection = pymysql.connect(
    host='localhost',
    user='your_username',
    password='your_password',
    database='your_database',
    charset='utf8mb4',
    cursorclass=pymysql.cursors.DictCursor
)

try:
    with connection.cursor() as cursor:
        # 执行SQL查询
        sql = "SELECT * FROM your_table"
        cursor.execute(sql)
        result = cursor.fetchall()
        print(result)
finally:
    # 关闭连接
    connection.close()
