Is there a way to make a progress bar in python? Or some bookstore ?. For example: if I have a function that in turn is composed of other functions or a cycle for which I must iterate in an immediate list. I would like to show the user how much time is left. Any ideas?
Use the progress package.
from progress.bar import Bar
bar = Bar('Processing', max=20)
for i in range(20):
# Do some work
bar.next()
bar.finish()
To install it use pip: pip install progress
If you do not want to install anything. A good implementation for python 2 is:
# -*- coding: utf-8 -*-
# Print iterations progress
def print_progress(iteration, total, prefix='', suffix='', decimals=1, bar_length=100):
"""
Call in a loop to create terminal progress bar
@params:
iteration - Required : current iteration (Int)
total - Required : total iterations (Int)
prefix - Optional : prefix string (Str)
suffix - Optional : suffix string (Str)
decimals - Optional : positive number of decimals in percent complete (Int)
bar_length - Optional : character length of bar (Int)
"""
str_format = "{0:." + str(decimals) + "f}"
percents = str_format.format(100 * (iteration / float(total)))
filled_length = int(round(bar_length * iteration / float(total)))
bar = '█' * filled_length + '-' * (bar_length - filled_length)
sys.stdout.write('\r%s |%s| %s%s %s' % (prefix, bar, percents, '%', suffix)),
if iteration == total:
sys.stdout.write('\n')
sys.stdout.flush()
