我在使用 tkinter 代码时遇到问题，该代码应该创建一个界面并具有一些按钮。 我有一些错误，但我似乎找不到它们。

我的代码如下：

from tkinter import*
import random
import time;

root = Tk()
root.geometry("1600x800+0+0")
root.title("Restruant Managment System")

text_Input = StringVar()
operator = ""


Tops = Frame(root, width = 1600,height = 50,bg="powder blue", relief=SUNKEN)
Tops.pack(side=TOP)

f1 = Frame(root, width = 800,height = 700, relief=SUNKEN)
f1.pack(side=LEFT)

f2 = Frame(root, width = 300,height = 700,bg="powder blue", relief=SUNKEN)
f2.pack(side=RIGHT)

当运行这段代码时，我有以下输出

我怎样才能让它工作？

【问题讨论】：

这在什么方面不起作用？ @SimonRaivid 将您的代码编辑为尽可能短，以重现您的问题，并清楚地说明什么不起作用。 【参考方案1】：

在行中

txtRefernce=Entry(f1,font=('arial', 16,'bold'),    
textvarible=rand, bd=10, 
insertwidth=4,bg="powder blue", justify='right')

您在 textvariable 参数中忘记了 A

txtRefernce=Entry(f1,font=('arial', 16,'bold'), 
textvariable=rand, bd=10, 
insertwidth=4,bg="powder blue", justify='right')

错误在-textvariable 参数中 尝试纠正这部分

在 第 195 行 中，您忘记了 #ffffff 颜色中的 #

当我在这里更正它时它工作得很好。

【讨论】：

能否请您给我看看您的代码，因为我的代码不起作用 你纠正我说的话了吗？如果是这样，它现在出现的错误消息是什么查看错误消息的内容非常重要。在您的情况下，它说：文件“E：\ Gui餐厅管理部分1.py”，第143行，在 bg="powder blue", justify='right') 然后我进入第 143 行检查程序中的错误，并意识到这只是一个打字错误（可能是复制粘贴）
