List available font families in `tkinter`

from tkinter import Tk, font
root = Tk()
font.families()

This question has been answered fully, but it's useful for me to be able to see what every font looks like so that I'm sure of which one I would like to use. In the interest of saving someone else from reinventing the wheel, I'll post my code here. As above, each font family is shown in a scrolling window. The difference is that each font in this code is printed in the font itself.

from tkinter import *
from tkinter import font

root = Tk()
root.title('Font Families')
fonts=list(font.families())
fonts.sort()

def populate(frame):
    '''Put in the fonts'''
    listnumber = 1
    for item in fonts:
        label = "listlabel" + str(listnumber)
        label = Label(frame,text=item,font=(item, 16)).pack()
        listnumber += 1

def onFrameConfigure(canvas):
    '''Reset the scroll region to encompass the inner frame'''
    canvas.configure(scrollregion=canvas.bbox("all"))

canvas = Canvas(root, borderwidth=0, background="#ffffff")
frame = Frame(canvas, background="#ffffff")
vsb = Scrollbar(root, orient="vertical", command=canvas.yview)
canvas.configure(yscrollcommand=vsb.set)

vsb.pack(side="right", fill="y")
canvas.pack(side="left", fill="both", expand=True)
canvas.create_window((4,4), window=frame, anchor="nw")

frame.bind("<Configure>", lambda event, canvas=canvas: onFrameConfigure(canvas))

populate(frame)

root.mainloop()

I hope this helps somebody.
