[havanagrawal]

Problem

Implement the the_tvdb_dot_com_id function in external_identifier

Prerequisites

• You know basic git, i.e. how to fork this repo, clone this repo, work on a branch and send a PR
• You have basic working knowledge of Python
• You are able to run Python on your machine
• You are familiar with basic web scraping (example: requests, bs4 (BeautifulSoup), etc)

How to Test

Simply run python3 external_identifier.py and it will run doctests. Ensure that the test for the_tvdb_dot_com_id passes.

Hints

• Try searching for some movie on https://www.thetvdb.com. What does the URL look like? You can use that to send a GET request.
• Feel free to add more arguments to the function if they help in increasing the confidence of the returned identifier.
