我正在嘗試獲取輸入并將輸入寫入文本文件以保存它。但是，我似乎無法將用戶輸入寫入文本文件。這是我的代碼：SaveUsername = open(r"C:\Users\Ty\Desktop\Login_sys\SaveUsername.txt","w+")SavePassword = open(r"C:\Users\Ty\Desktop\Login_sys\SavePassword.txt","w+")NewUsername = input("Please enter a username: ")NewPassword = input("Please enter a password: ")SaveUsername.write(NewUsername)print (SaveUsername.readline())SavePassword.write(NewPassword)print (SavePassword.readline())我正在打印 readline 以查看代碼是否被寫入并且它從來沒有。請幫助，謝謝。

嘗試這個
with open(r"SaveUsername.txt","w+") as SaveUsername:
NewUsername = input("Please enter a username: ")
SaveUsername.write(NewUsername)
with open(r"SavePassword.txt","w+") as SavePassword:
NewPassword = input("Please enter a password: ")
SavePassword.write(NewPassword)
with open(r"SaveUsername.txt" as SaveUsername:
print (SaveUsername.readline())
with open(r"SavePassword.txt") as SavePassword:
print (SavePassword.readline())

首先，您應(yīng)該在寫入文件后關(guān)閉文件，然后再讀取更改。您還應(yīng)該使用with open(...)它，因為它是一種更好的做法（出于多種原因）。這是您應(yīng)該使用的代碼：
with open(r"C:\Users\Ty\Desktop\Login_sys\SaveUsername.txt", "w") as SaveUsername:
NewUsername = input("Please enter a username: ")
SaveUsername.write(NewUsername)
with open(r"C:\Users\Ty\Desktop\Login_sys\SavePassword.txt", "w") as SavePassword:
NewPassword = input("Please enter a password: ")
SavePassword.write(NewPassword)
with open(r"C:\Users\Ty\Desktop\Login_sys\SaveUsername.txt", "r") as SaveUsername:
print(SavePassword.readline())
with open(r"C:\Users\Ty\Desktop\Login_sys\SavePassword.txt", "r") as SavePassword:
print(SavePassword.readline())
