Tkinter label 没有被破坏

Question

I wrote a little questionnaire and the questions won't be destroyed by clicking on the next or check button. Sometimes it works and sometimes not. It's really strange. The questions will be put on top of the old one. It's like a pile of questions and that's really annoying.

 def myLabeldestroy(self): myLabel01.destroy() def checkAnswer(self): ###Creation of random integers self.iniRand() ###Delete myLabel self.myLabeldestroy() self.mylabel(self.theories[self.qList][self.index][self.zero], 0, 1) ###Check whether answer is in used list or not if self.theories[self.qList] not in self.usedTheories: if self.gs[self.index][self.zero] not in self.used: ###Correct answer self.myEntry.get() == str(self.theories[self.qList][self.index][self.one]) self.used.append(self.gs[self.index][self.zero]) self.mylabel(self.answer[self.answerIndex], 2, 1) self.counter += self.one ###Point counter self.mylabel("Point counter " + str(self.counter), 4, 1) ###Wrong answer else: self.mylabel(self.reply[self.answerIndex], 2, 1) def nextAnswer(self): ###Creation of random integers self.iniRand() ###Delete myLabel self.myLabeldestroy() self.mylabel(self.theories[self.qList][self.index][self.zero], 0, 1) ###Check whether answer is in used list or not if self.theories[self.qList] not in self.usedTheories: if self.gs[self.index][self.zero] not in self.used: self.used.append(self.gs[self.index][self.zero]) self.counter -= self.one ###Point counter self.mylabel("Point counter " + str(self.counter), 4, 1)

Answer 1

I can advise you to use another method.If you are.pack() method, use pack_forget() or grid_forget() if you are using.grid().Learn more about it from here .

Answer 2

I've found out my mistake. I had to create two destroy methods.

 def myLabeldestroyStart(self): self.myLabelstart01.destroy() def myLabeldestroyQuestions(self): self.myLabelquestion01.destroy()
