3、插入数据

# python代码
from pymongo import MongoClient

client = MongoClient()

db = client.test

for i in range(1000):

    # 插入到restaurants表
db.restaurants.insert_one({"name{}".format(i): "street {}".format(1000-i)})

    # 插入到用户表
db.Users.insert_one({
    "姓名": "Melissa Ramsey",

    "性别": "girl",
    "地址": {
        "街道": "2640 Lyndon Street",

        "省份": "PA",
        "国家": "US",
    },
    '电话': "+1.6106863153",

# 插入到用户表，相对上一数据，增加了“男朋友”
db.Users.insert_one({
