# Setting a specific value to tqdm progress bar

I am a happy user of tqdm Python library. It's lightweight and with its with tqdm() as pbar clause or a wrapper for for cycle it's supper easy to use.

I was using something along these lines:

with tqdm(total=100) as pbar:
while statement:
cur_perc = get_current_percents()
pbar.update(cur_perc)
if cur_perc == 100:
break


function get_current_percents() could return something like this after all iterations: [0, 0, 1, 1, 1, 10, 20, 30, 50, 50, 50, 90, 100]. So if you used pbar.update(x), you would end up with a number 403, which is clearly not what I expected.

I solved that by editing the code as follows:

with tqdm(total=100) as pbar:
while statement:
cur_perc = get_current_percents()
pbar.update(cur_perc - pbar.n)  # here we update the bar of increase of cur_perc
if cur_perc == 100:
break


by this change, I could still conveniently use update method while having what I wanted.
