需要幫助解決和了解MongoDB中的幾個錯誤使用Pycharm

我正在學習python 3.0並使用它與mongodb一起嘗試製作博客，正如udemy教程所指示的那樣。但是，即使我完全按照視頻中所示的方式進行操作，但我並沒有得到正確的結果。我的Python代碼是：需要幫助解決和了解MongoDB中的幾個錯誤使用Pycharm

import pymongo 

uri="mongodb://127.0.0.1:56752" 

client=pymongo.MongoClient(uri) 

database=client["fullstack"] 

collections=database["student"] 

student=collections.find({}) 

for i in student: 

    print(i)

我已經檢查了當前的端口號，它與mongod的終端匹配：

2017-03-30T04:57:31.250+0530 I NETWORK [thread1] connection accepted from 127.0.0.1:56752 #1 (1 connection now open) 
2017-03-30T04:57:31.251+0530 I NETWORK [conn1] received client metadata from 127.0.0.1:56752 conn1: { application: { name: "MongoDB Shell" }, driver: { name: "MongoDB Internal Client", version: "3.4.2" }, os: { type: "Darwin", name: "Mac OS X", architecture: "x86_64", version: "16.4.0" } }

然而，上運行的代碼，它顯示在幾個誤區：

/Users/suprateem/Documents/Pycharm/venv/bin/python /Users/suprateem/PycharmProjects/terminal_blog/app.py 
Traceback (most recent call last):

    self._error_message(selector)) 
pymongo.errors.ServerSelectionTimeoutError: 127.0.0.1:56752: [Errno 61] Connection refused 

Process finished with exit code 1

在本教程中，顯示了我們之前創建的本地數據庫，即json類型結構。到目前爲止，我已經從本教程所面臨的區別是：

我不得不使用sudo mongod的正常運行，而他們使用的mongod
我不得不使用sudo killall -15關閉我的最後的mongod標籤
後啓動一個新的終端，當我使用pymongo的更新版本比一個視頻

殺mongod的過程

任何幫助將不勝感激。謝謝。

只需連接到mongodb：//127.0.0.1且無端口號 - MongoDB正在偵聽默認端口27017.您在日誌中看到的端口56752是您連接的客戶端臨時端口，忽略它。
