列表對象沒有屬性拆分

Question

基本上標題說：我試圖創建一個程序，檢測文件中的用戶名和密碼。但是，每當我運行它，它想出了這個錯誤：

Traceback (most recent call last): 
    File "C:/Users/tom11/Desktop/Data Login.py", line 33, in <module> 
    content = raw.split(",") 
AttributeError: 'list' object has no attribute 'split' 

下面是代碼的地方是哪裏錯了：

UCheck = "" 
PCheck = "" 
Username = input("Username: ") 
Attempts = 3 
while UCheck != "Y": 
    lines = True 
    f = open('Data.txt', 'r+') 
    while lines: 
     raw = f.readlines() 
     content = raw.split(",") 
     if len(raw) == 0: 
      print("That Username does not exist!") 
      Username = input("Username: ") 
     elif Username == content[0]: 
      UCheck == "Y" 
      lines = False 

這是什麼.txt文件內：

TheCloudMiner,Password123 
TestUser,TestPass 
Testing,Tester 
Username,Password 

我已閱讀了其他一些答案，但他們對我沒有幫助。任何幫助將非常感激。

Answer 1

readlines()返回字符串列表，而不是字符串。你想單獨申請每行split()，所以你應該遍歷它的東西，如

for line in open(...).readlines(): 
    username, password = line.split(",") 
    # rest of your code
