from pymongo import MongoClient
client = MongoClient("mongodb://username:password@localhost:27017/dbname")  # username:用户名，password：账号密码，localhost：数据库IP，dbname：数据库名
db = client.get_default_database()  # 获取数据库
collection = db.tableNames  # 获取数据库表名称：tableNames 

# 数据查询
datas = collection.find({'field': "value"})
for data in datas:
	print(data)
