我遇到的问题是应该创建一个接口并有一些按钮的tkinter代码。 我对某些事情有误，但我似乎无法找到它们。

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)
#===================Time============================

lblInfo = Label(Tops, font=('SHOWCARD GOTHIC',50, 'bold'),text="Restruant managment system",fg="Steel Blue", bd=10, anchor='w')
lblInfo.grid(row=0,column=0)
lblInfo = Label(Tops, font=('SHOWCARD GOTHIC',20, 'bold'),text=localtime,fg="Steel Blue", bd=10, anchor='w')
lblInfo.grid(row=1,column=0)
#=========================Calculator==============
def btnClick(numbers):
    global operator
    operator = operator + str(numbers)
    text_Input.set(operator)

def btnClearDisplay():
    global operator
    operator=""
    text_Input.set("")

def btnEqualsInput():
    global operator
    sumup =str(eval(operator))
    text_Input.set(sumup)
    operator=""

    x = random.radient(10908, 500876)
    randomRef = str(x)
    rand.set(randomRef)

    root.destroy()

当运行此代码时，我有以下输出

============== RESTART: E:\Gui restraurant managment part 1.py ==============
    Traceback (most recent call last):
      File "E:\Gui restraurant managment part 1.py", line 143, in <module>

        (widgetName, self._w) + extra + self._options(cnf))
    _tkinter.TclError: unknown option "-textvarible"
    >>>

我怎样才能让它发挥作用？

答案 0 :(得分：0)

第

行

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

您忘记了textvariable param中的A 

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

错误发生在-textvariable参数中 尝试更正此部分

另外在 195th 行中，您忘记了#颜色中的#ffffff

当我在这里纠正它时，它工作得很好。
