用python实现操作mongodb的插入和查找操作
python
import pymongo
client = pymongo.MongoClient("mongo://localhost:27017")
db = client["app"]
col = db["C1"]
# 插入一条数据
#user = {
# "name": "Sam",
# "age": 20,
# "email": "[email protected]"
#}
#res = col.insert_one(user)
#print(res.inserted_id)
# 插入多条数据
user = [{
"name": "Sam",
"age": 20,
"email": "[email protected]"
},
{
"name": "Peter",
"age": 21,
"email": "[email protected]"
},
{
"name": "Lily",
"age": 23,
"email": "[email protected]"
}
]
res = col.insert_many(user)
print(res.inserted_ids)
#查看所有数据
users = col.find()
for user in users:
# print(user)
print(user["name"])
# 条件查找
user_name = col.find({"name":"Sam"})
for user in user_name:
print(user)
# 大于20
user_age = col.find({"age":{"$gt":20}})
for user in user_age:
print(user)
# 正则包含a
user_name = col.find({"name":{"$regex":"a"}})
# 正则以S开头
user_name = col.find({"name":{"$regex":"^S"}})
for user in user_name:
print(user)
