wayback-machine-scraper VS waybackpy

You can very easily scrape pages from the web archive with this small package: wayback-machine-scraper. Getting historic snapshots of a webpage becomes a matter of a one-liner like:

There are tools that allow you to scrape websites archived by the Wayback Machine. Like this one for example: https://github.com/sangaline/wayback-machine-scraper

I ended up using waybackpy python module to retrieve archived URLs, it worked well. I think the feature you want for this is the "snapshots", but I didn't test this myself

I have read it as someone told me that it has a section for using waybackpy, a tool/library that I wrote and maintain.
