There is a button:

but1 = Button(icon, text="Show the solution...", font="Arial 14", command=show) but1.grid(column=1, row=3)

And there is an event handler when you click on it:

 def show(): lf = LabelFrame(icon, text="Solution", font='Arial 12') lf.grid(column=0, row=5, columnspan=4) Label(lf, text='1) A - B = {f1}\n' '2) B & A = {f2}\n' '3) (A - B) | (B & A) = {f3}\n' '4) ( (A - B) | (B & A) ) \ (C | B) = {rez}\n' 'Result: {rez}' .format(f1=log_oper.difference(self.A, self.B), f2=self.B & self.A, f3=(log_oper.difference(self.A, self.B))|(self.B&self.A), rez=initeq.initial_eq(self.A,self.B,self.C),font='Arial 14', justify=LEFT)).grid(column=0, row=5, sticky=W, columnspan=4)

The LabelFrame is created in the LabelFrame window with the text:

 '1) A - B = {f1}\n' '2) B & A = {f2}\n' '3) (A - B) | (B & A) = {f3}\n' '4) ( (A - B) | (B & A) ) \ (C | B) = {rez}\n' 'Result: {rez}'

And here is the question: How to make it so that when you click on a button, it is displayed step by step one item from that text? It can be either automatically or press the button 5 times.

  • What is log_oper ? Why not just self.A - self.B instead of log_oper.difference() ? - insolor
  • @insolor it doesn’t matter much - Artem Aleksandrovich
  • Usually it matters. Why make it difficult if you can do it simply? - insolor
  • You are right, but this does not solve my problem - Artem Aleksandrovich
  • one
    Answer vadim vaduha solves your problem, you just need to add format. - insolor

    • The answer is working, you only need to add format so that values ​​are displayed, something like this: i_text = iter(filter(bool, map(str.strip, Text.format(...).split('\n')) - insolor
    • since I have a set() , so split is not suitable for them - Artem Aleksandrovich
