>> import pymongo

2、mongo数据库的使用

>>> import pymongo>>> client = pymongo.MongoClient("localhost", 27017)>>> db = client.test>>> db.nameu'test'>>> db.my_collectionCollection(Database(MongoClient('localhost', 27017), u'test'), u'my_collection')>>> db.my_collection.insert_one({"x": 10}).inserted_idObjectId('4aba15ebe23f6b53b0000000')>>> db.my_collection.insert_one({"x": 8}).inserted_idObjectId('4aba160ee23f6b543e000000')>>> db.my_collection.insert_one({"x": 11}).inserted_idObjectId('4aba160ee23f6b543e000002')>>> db.my_collection.find_one(){u'x': 10, u'_id': ObjectId('4aba15ebe23f6b53b0000000')}>>> for item in db.my_collection.find():...     print(item["x"])...10811>>> db.my_collection.create_index("x")u'x_1'>>> for item in db.my_collection.find().sort("x", pymongo.ASCENDING):...     print(item["x"])...81011>>> [item["x"] for item in db.my_collection.find().limit(2).skip(1)][8, 11]
