Tom Hodson - Progress bars and log output in Jupyter notebooks

I wanted to have just one updatable line of output that would play nicely with a tqdm progress bar. After playing around with print(s, end="\r") I settled on using Ipython.display with a handle. The problem with the print approach is that it doesn’t work when the output is shorter than the previous line.

 1import time
 2import random
 3from tqdm.auto import tqdm
 4from IPython.display import display, Markdown
 5
 6info_line = display(Markdown(''), display_id=True)
 7
 8for x in tqdm(range(0,5), position = 0):  
 9    for y in tqdm(range(0,5), position = 1, leave=False):  
10        x = random.randint(1, 10)
11        b = "Loading" + "." * x
12        info_line.update(Markdown(b))
13        time.sleep(0.5)
