Check out the tqdm library. It's a very active project and there are examples on the github page on how to use it.

From the above site:

Instantly make your loops show a smart progress meter - just wrap any iterable with tqdm(iterable), and you're done!

from tqdm import tqdm
for i in tqdm(range(10000)):
    ...

Its very easy to use and one that i would recommend.

I have a function which I have used within some of my projects. You can adapt it for your requirements:

import sys
import time
def update_progress(progress):
    barLength = 56    # specify the length of your progressbar
    status = ""
    if isinstance(progress, int):
        progress = float(progress)
    if not isinstance(progress, float):
        progress = 0
        status = "error: progress var must be float\r\n"
    if progress < 0:
        progress = 0
        status = "Halt...\r\n"
    if progress >= 1:
        progress = 1
        status = "Done...\r\n"
    block = int(round(barLength*progress))
    text = "\rProgress: [{0}] {1}%".format( "#"*block + "-"*(barLength-block), int(progress*100))    
    sys.stdout.write(text)
    sys.stdout.flush()       # clear screen to update progress

Call it:

update_progress(0.5)  # update to 50%
# do some processing #
# you might want to call sleep method if your processing doesn't take so long in order to smooth the progress update
time.sleep(2)         # wait for two seconds to see progress
update_progress(1);   # update to 100%

Output:

Progress: [########################################################] 100%
