有没有办法在GUI中的python中编写上标？

这是我当前的代码，它显示在一个窗口中，但字面上按照我输入的方式打印它（显然）。但有没有办法写这些，所以他们显示为权力/指数？ “

questionNum = 0

#SET QUESTIONS HERE

questions = [0,"Given that y = x^4 + 6x^1/2, find dy/dx","Write down the value of 125^1/3","Fully factorise 9x^2 - 25","Find the value of 8^5/3"]

answer1 = [0,"4x^4 + 3x^1/2","25","(3x-5)(3x+5)","1/2"]

answer2 = [0,"4x^3 + 6x^1/2","1/5","(3x+5)(3x+5)","Answer 2 (4)"]

answer3 = [0,"4x^3 + 6x^-1/2","5","(3x-5)(3x-5)","Answer 3 (4)"]

answer4 = [0,"4x^3 + 1/2x^-3/2","125","(9x+5)(x-5)","Answer 4 (4)"]

这就是它的样子：

this is what it looks like 

rightanswers = [0,1,2,3,4]  #These are the correct answers
"

这是需要改变的一点。我已经添加了其余部分，以防您需要其中任何一个来查看正在发生的事情：

from tkinter import *   #The TKinter module imported in order to create the menus
import sys  #Invoke functions and statements - allows operations to work and searches for named modules i.e. TKinter
global questionNum  #Connections between functinos and arrays

questionNum = 0
#SET QUESTIONS HERE
questions = [0,"Given that y = x^4 + 6x^1/2, find dy/dx","Write down the value of 125^1/3","Fully factorise 9x^2 - 25","Find the value of 8^5/3"]  #This is the question bank which has been set up as an array
answer1 = [0,"4x^4 + 3x^1/2","25","(3x-5)(3x+5)","1/2"]   #These are the possible answers - this is where multiple choice answers would go
answer2 = [0,"4x^3 + 6x^1/2","1/5","(3x+5)(3x+5)","Answer 2 (4)"]
answer3 = [0,"4x^3 + 6x^-1/2","5","(3x-5)(3x-5)","Answer 3 (4)"]

Unicode在BMP中有上标数字，算术运算符和一些字母，由tcl / tk支持。见Wikipedia。在这些限制内，并给出支持字体，答案是肯定的。在Windows上，从IDLE运行，以下工作很好，看起来不错，但我希望tk字体更大，以便用我的眼睛轻松看到上标。

import tkinter as tk
root = tk.Tk()
# "4x^4 + 3x^1/2"
t1 = "4x\u2074 + 3x\u207b\u00b2"  # \u excapes, if needed
t2 = "4x⁴ + 3x⁻²"
label = tk.Label(root, text=t2)
label.pack()
