pymysql连接报错：

_init__() takes 1 positional argument but 5 positional arguments (and 1 keyword-only argument) were given

解决方法：

连接方法加属性名称，例

pymysql.connect("localhost", "root", "password", "database",charset="utf8")

改为

pymysql.connect(host="localhost", user="root", password="password", database="database",charset="utf8")
