连接mongo
默认连接本地mongo
from pymongo import MongoClient
client =MongoClient()
参数形式连接mongo
client = MongoClient(host='IP', port=27017) #端口号默认为27017是数值
URI形式连接mongo
client = MongoClient('mongodb://IP:27017')
创建数据库
#创建数据库,两种方式
db = client.peopleinfo
db = client['peopleinfo']
连接pydb数据库
import pymongo
client = pymongo.MongoClient(host='localhost', port=27017)
db = client['pydb']
创建数据表
和数据库一样,下面两种方式都可以
t = db.stu
t = db['stu']
插入数据
stu.insert({'_id':3,'name':'mog','age':20})
修改数据
stu.update({'_id':3},{'$set':{'name':'mongo'}})
查询数据
for cur in stu.find({'age':{'$gte':20}}):
print(cur)
删除数据
stu.delete_one({'_id':'2'})
