Question

你好，我是新来的论坛。

我有很多使用python的经验但没有使用tkinter。

这是我的代码：

from tkinter import *


def Done():
     celEntry = celTempVar.get()
     print(str(celEntry))
     f = open("Name", "w")
     f.write(str(celEntry))
     f.close()

def Yes():


     celEntry = Entry (mainframe, width = 10, bd = 5, textvariable = celTempVar)
     celEntry.grid(row = 3, column = 1, pady = 10, sticky = NW, padx = 125 )

     titleLabel = Label (mainframe, text = "Enter Name", font = ("Arial", 12, "bold"), justify = LEFT)
     titleLabel.grid(row = 2, column = 1, columnspan = 3, pady = 10, padx = 20)

     DoneButton = Button (mainframe, text = "Done", font = ("Arial", 8, "bold"), relief = RAISED, bd=5, justify = CENTER, highlightbackground = "red", overrelief = GROOVE, activebackground = "black", activeforeground="blue", command = Done)
     DoneButton.grid(row = 4, column = 1, ipady = 8, ipadx = 12, pady = 5, sticky = NW, padx = 55)




###MAIN###
root = Tk()
root.title("Text Adv")
mainframe = Frame(root)
mainframe.grid()

celTempVar = StringVar()
celTempVar.set("")

titleLabel = Label (mainframe, text = "Text adventure", font = ("Arial", 20, "bold"), justify = CENTER)
titleLabel.grid(row = 1, column = 1, columnspan = 3, pady = 10, padx = 20)


f = open("Name", "r")
Name = f.read()

if Name == "":
     celEntry = Entry (mainframe, width = 10, bd = 5, textvariable = celTempVar)
     celEntry.grid(row = 3, column = 1, pady = 10, sticky = NW, padx = 125 )

     titleLabel = Label (mainframe, text = "Enter Name", font = ("Arial", 12, "bold"), justify = LEFT)
     titleLabel.grid(row = 2, column = 1, columnspan = 3, pady = 10, padx = 20)

     DoneButton = Button (mainframe, text = "Done", font = ("Arial", 8, "bold"), relief = RAISED, bd=5, justify = CENTER, highlightbackground = "red", overrelief = GROOVE, activebackground = "black", activeforeground="blue", command = Done)
     DoneButton.grid(row = 4, column = 1, ipady = 8, ipadx = 12, pady = 5, sticky = NW, padx = 55)

else:
     titleLabel = Label (mainframe, text = "Start new game?", font = ("Arial", 12, "bold"), justify = LEFT)
     titleLabel.grid(row = 2, column = 1, columnspan = 3, pady = 10, padx = 20)

     DoneButton = Button (mainframe, text = "Yes", font = ("Arial", 8, "bold"), relief = RAISED, bd=5, justify = CENTER, highlightbackground = "red", overrelief = GROOVE, activebackground = "black", activeforeground="blue", command = Yes)
     DoneButton.grid(row = 3, column = 1, ipady = 8, ipadx = 12, pady = 5, sticky = NW, padx = 55)

     DoneButton = Button (mainframe, text = "No", font = ("Arial", 8, "bold"), relief = RAISED, bd=5, justify = CENTER, highlightbackground = "red", overrelief = GROOVE, activebackground = "black", activeforeground="blue", command = Done)
     DoneButton.grid(row = 4, column = 1, ipady = 8, ipadx = 12, pady = 5, sticky = NW, padx = 55)

root.mainloop()

所以我想要的是在运行Yes（）时擦除屏幕。

简单但有其他答案，我真的不明白。

如果你可以在我的代码中实现一个很棒的擦除功能。

Atm我只是试验其他人的代码，这就是为什么变量名称就像CeltoFar之类的东西。

如果您不理解我的意思是擦除，如删除gui中的所有小部件，或删除特定的小部件。

请不要留下任何仇恨！

是的，我喜欢新的段落：）

您可以销毁小部件，这会将其从屏幕上删除。只需调用窗口小部件上的destroy方法即可。销毁窗口小部件时，其所有子窗口小部件也将被销毁。因此，例如，如果要销毁帧中的所有小部件，则只需要销毁该帧。

如果您只想将其从屏幕上删除而不是销毁它们，则可以调用grid_remove，grid_forget，pack_forget或place_forget小部件，具体取决于方式你把它们放在屏幕上。

当然，您也可以重置窗口小部件的值，而不是删除它们或从屏幕上删除它们。如何执行此操作取决于窗口小部件的类型，但可以重新配置所有窗口小部件而不会被销毁。

Tkinter屏幕擦拭，具体
