Question

我想将数据从 json 传输到 mysql，因为我安装了 python 库 MySQLdb 。导入成功但连接时出错

>>> import MySQLdb
>>> db=MySQLdb.connect(passwd="king123",db="thangs")

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    db=MySQLdb.connect(passwd="king123",db="thangs")
  File "C:\Python27\lib\site-packages\MySQLdb\__init__.py", line 81, in Connect
    return Connection(*args, **kwargs)
  File "C:\Python27\lib\site-packages\MySQLdb\connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
OperationalError: (2003, "Can't connect to MySQL server on 'localhost' (10061)")

>>> import _mysql

    db=_mysql.connect()
