Hands-On Blockchain for Python Developers

Creating a bootstrap script

This script is used to load data to make the development of our application easier. We can download free videos from https://videos.pexels.com/. Create a stock_videos directory adjacent to the videos_sharing_smart_contract directory and download some MP4 files to that stock_videos directory. In my case, I downloaded more than 20 videos.

After downloading some data, we will create a script called bootstrap_videos.py. Refer to the code file at the following GitLab link for the full code: https://gitlab.com/arjunaskykok/hands-on-blockchain-for-python-developers/blob/master/chapter_12/bootstrap_videos.py:
