Answer 1

Assuming "root" is your Tk Window, here's the simplest example on how you could do it :

p = Progressbar(root,orient=HORIZONTAL,length=200,mode="determinate",takefocus=True,maximum=100)
p.pack()            
for i in range(100):                
    p.step()            
    root.update()

Don't forget to import Progressbar :

from tkinter.ttk import Progressbar
