所以我一直在關注一個在線教程并自己撰寫它，這樣我就可以習慣這些錯誤，但我現在有一個錯誤“未知選項“-Command”
它似乎只影回應該關閉視窗的確定按鈕。
任何有助于理解問題以及如何解決問題的幫助將不勝感激
為了制作用于登錄的用戶檔案，只需創建一個標題為“用戶”的檔案，檔案中的文本為：用戶 123
這將是登錄的用戶名和密碼
代碼如下：
from tkinter import *
import os
def delete2():
screen3.destroy()
def delete3():
screen4.destry()
def delete4():
screen5.destroy()
def login_sucess():
global screen3
screen3 = Toplevel(screen)
screen3.title("Sucess")
screen3.geometry("150x100")
Label(screen3, text = "Login Sucess").pack()
Button(screen3, text = "OK", Command =delete2).pack()
def password_not_recognised():
global screen4
screen4 = Toplevel(screen)
screen4.title("Sucess")
screen4.geometry("150x100")
Label(screen4, text = "Password Error").pack()
Button(screen4, text = "OK", Command =delete2).pack()
def user_not_found():
global screen5
screen5 = Toplevel(screen)
screen5.title("Sucess")
screen5.geometry("150x100")
Label(screen5, text = "User Not Found").pack()
Button(screen5, text = "OK", Command =delete2).pack()
def login_verify():
username1 = username_verify.get()
password1 = password_verify.get()
username_entry1.delete(0, END)
password_entry1.delete(0, END)
list_of_files = os.listdir()
if username1 in list_of_files:
file1 = open(username1, "r")
verify = file1.read().splitlines()
if password1 in verify:
login_sucess()
else:
password_not_recognised()
else:
user_not_found()
def login():
global screen2
screen2 = Toplevel(screen)
screen2.title("Login")
screen2.geometry("300x250")
Label(screen2, text = "please enter details below to login").pack()
Label(screen2, text = "").pack()
global username_verify
global password_verify
username_verify = StringVar()
password_verify = StringVar()
global username_entry1
global password_entry1
Label(screen2, text = "Username * ").pack()
username_entry1 = Entry(screen2, textvariable = username_verify)
username_entry1.pack()
Label(screen2, text = "").pack()
Label(screen2, text = "Password * ").pack()
password_entry1 = Entry(screen2, textvariable = password_verify)
password_entry1.pack()
Label(screen2, text = "").pack()
Button(screen2, text = "Login", width = 10, height = 1, command = login_verify).pack()
def main_screen():
global screen
screen = Tk()
screen.geometry("300x250")
screen.title("Remote Monitoring Site 1")
Label(text = "Remote Monitoring Site 1", bg = "grey", width = "300", height = "2", font = ("Calibri", 13)).pack()
Label(text = "").pack()
Button(text = "Login", width = "30", height = "2", command = login).pack()
Label(text = "").pack()
Button(text = "Register", width = "30", height = "2", command = register).pack()
screen.mainloop()
main_screen()
完整錯誤如下：
self.tk.call(_tkinter.TclError: 未知選項“-Command”
我嘗試過研究，但沒有找到解決我的問題的方法。
uj5u.com熱心網友回復：
python 函式的選項區分大小寫，含義command（這是您要設定的選項）與Command. 在所有情況下更改Button(screen4, text = "OK", Command =delete2).pack()為。Button(screen4, text = "OK", command =delete2).pack()
