How do I implement a progress bar

Question

How do I implement a progress bar in jupyter-notebook?

I've done this:

count = 0 max_count = 100 bar_width = 40 while count <= max_count:     time.sleep(.1)     b = bar_width * count / max_count     l = bar_width - b     print '\r' + u"\u2588" * b + '-' * l,     count += 1 

Which is great when I have access to a loop in which to print stuff out. But does anyone know of anything clever to run a progress bar of some sort asynchronously?

Here is a solution (following this).

from ipywidgets import IntProgress from IPython.display import display import time  max_count = 100  f = IntProgress(min=0, max=max_count) # instantiate the bar display(f) # display the bar  count = 0 while count <= max_count:     f.value += 1 # signal to increment the progress bar     time.sleep(.1)     count += 1 

If the value that's changing in the loop is a float instead of an int, you can use ipwidgets.FloatProgress instead.
