import pymongo
'''
>>> from pymongo import Connection #导入模块
>>> con = Connection()
连接方法较多
'''
con = pymongo.Connection('127.0.0.1',27017)
'''
创建数据库
'''
db = con.mydb
'''
创建类似与表的东西
'''
posts = db.post
a = {'id':1,'name':'pymongo'}
b = {'id':2,'name':'python'}
'''
数据库的基本操作增删改查,没有commit一说

'''
posts.insert(a)
posts.insert(b)
ps = posts.find()

count = posts.count()
print count

post = posts.find_one()
print post

for i in ps:
print i
