我有一个非常基本的程序可以输出一串值,但我不太确定如何清除这些值。目前我已经设置好了,所以我只需退出窗口并开始一个新窗口,这样我就不会一直重写新值。有没有一种简单的方法可以添加另一个按钮,该按钮只显示“清除”之类的内容并确实做到了这一点?我的代码如下:
def create_widgets(self):
self.entryLabel = Label(self, text="Please enter a list of numbers:")
self.entryLabel.grid(row=0, column=0, columnspan=2)
self.listEntry = Entry(self)
self.listEntry.grid(row=0, column=2, sticky=E)
self.entryLabel = Label(self, text="Please enter an index value:")
self.entryLabel.grid(row=1, column=0, columnspan=2, sticky=E)
self.indexEntry = Entry(self)
self.indexEntry.grid(row=1, column=2)
self.runBttn = Button(self, text="Run Function", command=self.psiFunction)
self.runBttn.grid(row=2, column=0, sticky=W)
self.answerLabel = Label(self, text="Output List:")
self.answerLabel.grid(row=2, column=1, sticky=W)
self.clearBttn = Button(self, text="Clear Output", command=)
self.clearBttn.grid(row=3, column=0, sticky=W)
def clear():
config.self.entryLabel(text="")
tk.Button(text="write", command=write).grid()
tk.Button(text="clear", command=clear).grid()
self.clearBttn = Button(self, text="Clear Output", command=clear)
self.clearBttn.grid(row=3, column=0, sticky=W)
