1.安裝pymongo：

pip3 install pymongo

2.pymongo的簡單用法：

# /usr/bin/env python3
import pymongo


class Mymongo(object):
    def __init__(self, host, port=27017):
        try:
            self.conn = pymongo.MongoClient(host=host, port=port)
        except Exception as e:
            print("連接失敗", e)
        else:
            print(‘連接成功‘)

    def add(self, p_dict):
        res = self.conn.testdb.testcol.insert(p_dict)  # insert需要傳入字典
        if res:
            print(‘插入成功‘)

    def show(self):
        res = self.conn.testdb.testcol.find()  # find()返回一個可叠代對象
        for i in res:
            print(i)

    def mod(self, before, after):   # 需要傳入字典
        res = self.conn.testdb.testcol.update(before, after)
        if res:
            print("修改成功", res)

    def rem(self, p_dict):
        res = self.conn.testdb.testcol.delete_one(p_dict)
        if res:
            print(‘刪除成功‘)

if __name__ == "__main__":
    mymongo = Mymongo(‘192.168.26.135‘)
    mymongo.add({"name": ‘Tom‘})
    mymongo.show()
    mymongo.mod({"name": ‘Tom‘}, {"name": ‘Jerry‘})
    mymongo.show()
    mymongo.rem({"name": ‘Jerry‘})
    mymongo.show()
