网上很多代码给的连接数据库是连的sqlite的例子，按照以下方法写没问题，我还用了ORM
# -*- coding:utf-8 -*-
from sqlalchemy import create_engine,Column,Integer,String
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
dbPath = 'sqlite:////Users/mbp/Downloads/JA.db'
engine = create_engine(dbPath,echo=True)
Session = sessionmaker(bind=engine)
session = Session()
Base = declarative_base()
class Actresses(Base):
__tablename__ = 'JA_NAME'
id = Column('id', Integer, primary_key=True, autoincrement=True)
name = Column('NAME_URL',String)
nameUrl = Column('NAME',String)
act = session.query(Actresses).all()
print act
如果有同学依葫芦画瓢把数据库地址直接改成mysql的连接就会报错
raise EnvironmentError("%s not found" % (mysql_config.path,))
原因是使用sqlalchemy连接mysql的话光安装sqlalchemy这个库还不够，还要安装mysql-python这个驱动库

装好后，代码中也不需要
import，直接运行下就好了，完整代码如下，重点就是在安装了sqlalchemy之后还要再安装下mysql-python
# -*- coding:utf-8-*-

print_order = Table('print_order', metadata,
