我需要更大的字体在Python空闲

import tkinter as tk
from tkinter import font

window = tk.Tk()
window.title("调整字体大小")

label = tk.Label(window, text="这是一段文本", font=("Arial", 12))
label.pack()

def change_font_size(value):
    new_font_size = int(value)
    label.config(font=("Arial", new_font_size))

font_size_slider = tk.Scale(window, from_=10, to=30, orient=tk.HORIZONTAL, command=change_font_size)
font_size_slider.pack()

window.mainloop()
