Load external font and does not show font in the window

[ATARI_LIVE]

Wow and thanks again... Those last code a bit hard to understand how it works but I need more learning...
However, I did install the font and code with Tkinter can't see it. here what I did:
> cp Digital-7.ttf /home/pi/.local/fonts
> fc-cache -f -v

did I miss something?

Also, I use font list codes from the internet it show me list a lot but no Digital-7. here the code that I copied from the internet:

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()
