Download online book with web scraper in Python

This is a pretty simple project, I would like someone to develop a web scraper or something similar (ideally in Python) to download books which are available online for free but in a format which can't be downloaded seamlessly. There are 7 books, all in the same format, whose images in high definition I would like to have shared with me (each book is about ~200 pages), and also I would like the code to be shared that I could eventually use in the future. If the download and sharing of all the boooks becomes unfeasible due to way too large data, if an application is shared which is intuitive and works fine, only the code would already suffice.
