[Tkinter] scrolling text in tkinter

[metulburr]

Are you set on tkinter? Or can it be any library? 
Often use this as a credit screen for resources, developers, etc. for games. Thus the reason why its in pygame.

import pygame as pg
 
pg.init()
 
text_list = '''I'm Henry the eighth, I am
Henry the eighth, I am, I am
I got married to the widow next door
She's been married seven times before
 
And every one was an Henry (Henry)
She wouldn't have a Willy or a Sam (No Sam)
I'm her eighth old man, I'm Henry
Henry the eighth I am
 
Second verse, same as the first
 
I'm Henry the eighth, I am
Henry the eighth, I am, I am
I got married to the widow next door
She's been married seven times before
 
And every one was an Henry (Henry)
She wouldn't have a Willy or a Sam (No Sam)
I'm her eighth old man, I'm Henry
Henry the eighth I am
 
I'm Henry the eighth, I am
Henry the eighth, I am, I am
I got married to the widow next door
She's been married seven times before
 
And every one was an Henry (Henry)
She wouldn't have a Willy or a Sam (No Sam)
I'm her eighth old man, I'm Henry
Henry the eighth I am
 
H-E-N-R-Y
Henry (Henry)
Henry (Henry)
Henry the eighth I am, I am
Henry the eighth I am
Yeah!
