pymongo直接使用pip安装：pip install pymongo

示例代码

from pymongo import MongoClient

mongo_conn = MongoClient(host='localhost', port=27017)
mongo_db = mongo_conn.get_database("test")  # 指定数据库
coll = mongo_db.get_collection("people")  # 指定集合

new_people = {'name': "小明", 'age': 13}

# 增加
coll.insert_one(new_people)
coll.insert_many([{"name": "小红", 'age': 11}, {"name": "小蓝", "age": 12}])

# 查询
record = coll.find_one({'name': "小明"})

# 修改
coll.update_one(record, {
    "$set": {"age": 22, '成绩': 101},  # "$set"是固定写法，后面字典里的是覆盖的新值
})

# 删除
coll.delete_one({"name": "小红"})
