Hi, initial only sets the initial offset for iteration display (I.e.
it'll start displaying 30/100 in your example, then go on to 130/100.) what
you need is to let (x)range know you want to start at 30 as well.

trange(30, 100, initial=30, ...)

do something else for to_mongo_pbar

to_mongo_pbar.update(1)
to_mongo_pbar.close()

for this snippet I would expect the iteration(i) start from 30 and finish
at 99, however it extend the counter to 129
is it a bug or expected behaviour?

to Mongo: 130it [00:10, 9.83it/s]

@casperdcl

import tqdm
from time import sleep

to_mongo_pbar = tqdm.trange(30, 100, desc='to Mongo', initial=30)
for i in tqdm.trange(30, 100, desc='imputed', initial=30):
  sleep(0.1)
  # do something else for to_mongo_pbar
  to_mongo_pbar.update(1)
to_mongo_pbar.close()

this is still failing, it starts at 30/70, continue to exeeds the remain 30 it , which I think it should be 30/100

to Mongo: 100it [00:07,  9.63it/s]

ah sorry, the length of your iterable is 70, so you don't need initial.

for x in tqdm.trange(30, 100):
   ...
# or
for x in tqdm.tqdm(range(30, 100)):
  ...

the displayed bar would go from 0/70 to 70/70. I think currently the only way to start at 30/100 and go to 100/100 (if that's what you really really really want) is:

r = range(100)[30:]
for x in tqdm.tqdm(r, initial=30):
  ...

either way, I've assumed you want x to start at 30 and finish at 99.

He can also set the total manually, that's what I did (I often used initial to get back from a pause between two sections of code):

import time
from tqdm import trange

upper_bound=100
current=30
for x in trange(current, upper_bound, total=upper_bound, initial=current):
    time.sleep(0.1)

Please feel free to report if this solved your issue, or open it again if not!

The range works perfectly the problem the iteration speed the iteration speed at the end counts from 0-100 instead of just from 30-100
