Python不會讀取文本文件

Question

我試過在網上尋找解決這個問題的方法，但沒有任何效果。

Python 應該讀取一個名為“directory.txt”的文件，但它不斷出現空白或說：

<_io.TextIOWrapper name='directory.txt' mode='r' encoding='cp1252'>

這個想法是它應該讓用戶將姓名和電子郵件添加到 txt 文件中，允許他們“讀取”文件或“添加”到它。

代碼：

command = input("What would you like to do? Read or add? >> ")
programactive = True

if command == "Read" or "read":

    directory = open('directory.txt', 'r')
    directory.read()
    print(directory)
    directory.close()


elif command == "Add" or "add":

    while programactive == True:
        directory = open('directory.txt', 'a')
        new_name = input("Add a new name to the list. >> ")
        new_email = input("Add a new email for that name. >> ")
        combined = new_name + ", " + new_email
        directory.write(combined)
        cont = input("Add more? Yes or No >> ")
        if cont == "No" or "no":
            directory.close()
            programactive = False

Answer 1

我在這里寫了代碼，它正在工作：

import io

programactive = True

command = input("What would you like to do? Read or add? >> ")

if command == "Read" or command == "read":
   directory = open("directory.txt", 'r')
   read_string = directory.read()
   print(read_string)
   directory.close()
elif command == "Add" or command == "add":
   while programactive == True:
      directory = open('directory.txt', 'a')
      new_name = input("Add a new name to the list. >> ")
      new_email = input("Add a new email for that name. >> ")
      combined = new_name + ", " + new_email + ", "
      directory.write(combined)
      cont = input("Add more? Yes or No >> ")
      if cont == "No" or "no":
         directory.close()
         programactive = False
else:
   print("Invalid command...")

我在這段代碼中看到的一些問題：

1）您正在打印指向directory對象的內存位置的指針，而不是其內容。
2) 您的Read和Add和No條件邏輯沒有正確檢查這兩個條件。 3）您不會在每個添加的條目后附加換行符，因此文本將顯示在一行上，而不是分隔符。

對於#1，您只需要將directory.read()的內容存儲在一個字符串變量中，然后打印該字符串，而不是打印對象本身。 對於#2，當您有多個相等條件時，您必須明確定義相等的兩邊（例如if command == "Read" or command == "read":而不僅僅是if command == "Read" or "read:"對於#3，您只需要在“組合”變量中添加一個\\n即可。

嘗試以下代碼，並測試“添加”功能，然后檢查文件以確保添加的文本按照您的預期進行格式化：

command = input("What would you like to do? Read or add? >> ")
programactive = True

if command == "Read" or command == "read":

    directory = open('directory.txt', 'r')
    contents = directory.read()
    print(contents)
    directory.close()


elif command == "Add" or  command == "add":

    while programactive == True:
        directory = open('directory.txt', 'a')
        new_name = input("Add a new name to the list. >> ")
        new_email = input("Add a new email for that name. >> ")
        combined = "\n" + new_name + ", " + new_email
        directory.write(combined)
        cont = input("Add more? Yes or No >> ")
        if cont == "No" or cont == "no":
            directory.close()
            programactive = False
