Python 我试图在tk窗口中的函数错误中添加图像：-image"；pyimage4“；不'；不存在

这是我的密码：

global ad4
global background
global background_l


def getvals():

    print(f"the value of username is {uservalue.get()}")
    print(f"the value of password is {passvalue.get()}")
    if (uservalue.get()).casefold()=="avvh".casefold() and passvalue.get()=="vhjbjh":
       
        b=Tk()
        b.geometry("600x400")

        ad4 = Image.open("My Post.jpg")
        ad4 = ad4.resize((600, 400), Image.ANTIALIAS)
        background = ImageTk.PhotoImage(ad4)
        background_l = Label(b,image=background).pack()
        background_l.place(x=0, y=0, relwidth=1, relheight=1)

       
       
       
        b.mainloop()
        try:
            label(a).destroy()
        except:
            pass
    else:
        c=Label(a,text="incorrect pass or user name",fg="red").grid()

错误：

 Exception in Tkinter callback
 Traceback (most recent call last):
   File "C:\python 3.8.1\lib\tkinter\__init__.py", line 1883, in __call__
     return self.func(*args)

此错误通常在多次创建

Tk（）

时发生，对于辅助窗口，请将

Tk（）

替换为

Toplevel（）

这是否回答了您的问题？谢谢，这对我有用。
