    host=“你的数据库地址”,
    user=“用户名”,password=“密码”,
    database=“数据库名”,
    port="",

# 指定以dict形式返回,默认以元祖形式
conn = pymysql.connect(**mysql_connect_dict,cursorclass=pymysql.cursors.DictCursor)
print(conn)

# 创建游标
cursor = conn.cursor()

# 执行SQL,并返回收影响行数
effect_row = cursor.execute("select * from test1")
print(effect_row)  # 6条记录


# 关闭游标
cursor.close()
# 关闭连接
conn.close()
