python - Error Keyerror 255 when executing pymysql.connect -


here code

import pymysql pymysql.connect(     host='localhost',     port=3306,     user='root',     password='idontwannasay',     db='idontwannashow',     charset='utf8' )

and error traceback was:

data :::::b'\xff\x02\x00\xff\x81\x15'....##### add near line 1279 print("data :::::%s...."%data[i:i+6]) traceback (most recent call last):   file "c:\users\123\desktop\pymysqldebug.py", line 8, in <module>     charset='utf8'   file "d:\program files (x86)\python\python35\lib\site-packages\pymysql\__init__.py", line 90, in connect     return connection(*args, **kwargs)   file "d:\program files (x86)\python\python35\lib\site-packages\pymysql\connections.py", line 709, in __init__     self.connect()   file "d:\program files (x86)\python\python35\lib\site-packages\pymysql\connections.py", line 934, in connect     self._get_server_information()   file "d:\program files (x86)\python\python35\lib\site-packages\pymysql\connections.py", line 1279, in _get_server_information     self.server_charset = charset_by_id(lang).name   file "d:\program files (x86)\python\python35\lib\site-packages\pymysql\charset.py", line 39, in by_id     return self._by_id[id] keyerror: 255

seems struct.unpack method parse '\xff\' 255 , assigned self.server_language, whatever non-null charset argument passed.

is mysql version problem?(version 8.0.1-dmr)

the problem can referred pull request 591
