python 连接mongo数据库，进行简单的增删该查
实例：
# -*- coding: cp936 -*-
import pymongo
dictSearContion = {'STATE_1':1, 'STATUS':1}
client = pymongo.MongoClient("192.168.0.103", 27017)
replyDB = client.REPLY
topicDB = client.TOPIC
def getExcelTopics(collectionName):
topics = topicDB.TOPIC_COL.find(dictSearContion)
for i in topics:
print i
if __name__=='__main__':
getExcelTopics("TOPIC_COLL")
