【问题描述】：
我正在尝试运行以下代码以将 symbols 变量的组件添加到名为 securities_master 的数据库中。我之前发布了这个问题并修复了大量错误，但是，我仍然收到以下错误：
Traceback (most recent call last):
File "C:/Users/Nathan/.PyCharmCE2018.1/config/scratches/scratch.py", line 28, in <module>
insert_btc_symbols(symbols)
File "C:/Users/Nathan/.PyCharmCE2018.1/config/scratches/scratch.py", line 15, in insert_btc_symbols
con = MySQLdb.connect(host=db_host,user=db_user,db=db_name) #,passwd=db_pass

super(Connection, self).__init__(*args, **kwargs2)
_mysql_exceptions.OperationalError: (1251, 'Client does not support authentication protocol requested by server; consider upgrading MySQL client')
Process finished with exit code 1
我尝试通过没有密码的用户和 root 用户以及密码的公钥进行连接，但均无济于事。以下是我正在执行的代码：
import datetime
import MySQLdb
from math import ceil
def obtain_btc():
now = datetime.datetime.utcnow()
symbols = ['BTC', 'Crypto', 'Bitcoin', 'No Sector', 'USD', now, now]
return symbols
def insert_btc_symbols(symbols):
db_host = 'localhost'
db_user = 'natrob2'
#db_pass = ''
db_name = 'securities_master'
con = MySQLdb.connect(host=db_host,user=db_user,db=db_name) #,passwd=db_pass
column_str = "ticker, instrument, name, sector, currency, created_date, last_updated_date"
insert_str = (("%s, ")*7)[:2]
final_str = ("INSERT INTO symbol (%s) VALUES (%s)" % (column_str,insert_str))
print (final_str,len(symbols))
with con:
cur = con.cursor()
for i in range(0,int(ceil(len(symbols)/100.0))):
cur.executemany(final_str,symbols[i*100:(i+1)*100-1])
if __name__ == "__main__":
symbols = obtain_btc()
insert_btc_symbols(symbols)
