conn.close()

having set charset but it is not useful,how can i insert Chinese into mysql

Answer 1

charset is a mysql database character set name that needs to be converted to a python encoding. pymysql has a large list of them in charset.py. Rather perversely, pymysql either spits back the charset name you passed in or raises the non-obvious error you see. In the pymysql world, "utf8" is a valid character set, but "utf-8" is not. So, just change your connect to

conn = pymysql.connect(host='127.0.0.1', port=3306, user='root',
    passwd='123456',db='home', charset="utf8")
