tqdm for a For Loop in Python

Question

I am using tqdm to track progress for a for loop in python.

import numpy as np
from tqdm import tqdm 

x = np.arange(20000000)

x_30 = []

for _x in tqdm(x):
    x_30.append(_x**30)

The progress bar looks like the following.

Can you please explain the progress bar for me? I don't really understand it.

Answer 1

The format of the bar is

{progress in percentage} | {bar} | {processed}/{total} [{elapsed time}<{remaining time}, {number of iterations per seconds} it/s]

You can find further information in the documentation, under bar_format.
