I'm trying to display a progress bar in a jupyter notebook with a bold description preceding the bar.

for i in tqdm(range(10), desc='\x1b[1mglobal progress'):
    time.sleep(.2)

seems to produce

I tried different options, qqdm and rich seem to work, but the former is stuck to 4 years ago, the latter seems to have a little too much overhead.

Following the comments I did this:

for i in tqdm(range(10), desc=tqdm.write('\x1b[1m global progress', end="")):
    time.sleep(.2)

which renders the text in bold, but introduces an unwanted newline. The end="" argument does not seem to have any effect. Actually I have exactly the same result if I use the built-in print function

Thanks for any help

• ANSI escape code \x1b[1m is being interpreted as part of the string, rather than as a formatting code use tqdm.write – steve-ed Commented Mar 10 at 15:10

• thanks @steve-ed, see edited question please. What am I missing? – user2078621 Commented Mar 10 at 15:35
• actually, this seems to be Jupyter notebook specific. On IPython it is working – user2078621 Commented Mar 10 at 15:48

For those wanting to use this with tqdm.notebook - the Jupyter Notebook progressbar decorator for iterators, you'll need both tqdm and ipywidgets installed, then try:

from tqdm.notebook import tqdm
import time
for i in tqdm(range(5), desc='
