How do I implement a progress bar

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.
