Below is the working of populate_db.py after modification

Thanks for this, but this introduces too many dependencies that are not specified -- and eventually limits the applicability.
And, as was stated in #34 the gain is only for the developer.

[shivanshuraj1333]

I have removed all unwanted dependencies. Only one extra dependency is needed to be installed i.e. tqdr. It is to be noted that the process took 1h 53min to complete, without progress bar it is very inconvenient to proceed and I have followed general method to display progress.
If this fix is able to resolve the issue please merge or else tell me any other probable solution.

@zvr please review the changes once again.
Thank you!

1h 53min is completely unreasonable!

I made a single-line patch in #43 and populate now takes 12sec on my laptop...
Definitely no need for extra code for something like this.
