python MySQLdb连接MySQL数据库报错(2003, "Can't connect to MySQL server on 'localhost' (10061)")解决办法

navicat连接MySQL数据库正常，python使用MySQLdb模块连接MySQL数据库时报错如下：

import MySQLdb
db = MySQLdb.connect('localhost','root','123456','myDB',charset='utf8')

Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
db = MySQLdb.connect('localhost','root','123456','SRS',charset='utf8')
File "F:\Python2.7.6\lib\site-packages\MySQLdb\__init__.py", line 81, in Connect
return Connection(*args, **kwargs)
File "F:\Python2.7.6\lib\site-packages\MySQLdb\connections.py", line 193, in __init__
super(Connection, self).__init__(*args, **kwargs2)
OperationalError: (2003, "Can't connect to MySQL server on 'localhost' (10061)")

解决办法：将“localhost”改为“127.0.0.1”，如下问题解决：

>>> ================================ RESTART ================================
>>>
>>> import MySQLdb
>>> db = MySQLdb.connect('127.0.0.1','root','123456','SRS',charset='utf8')
>>>
