Create Python script to extract full page URLs from Google Books (Open Access-Public Domain items)

I need a Python 3.6 script which will: 1) work through a large .txt file list of Google URLs, e.g. [login to view URL] [login to view URL] [login to view URL] 2) Extract the URLs (including SIG= elements) for every page within the above IDs, including the pages before the front cover where applicable. e.g. [login to view URL] [login to view URL] 3) Outputs the list of URLs for each book id as a single text file, with each page URL on its own line. The text file should be named after each BookID, e.g. [login to view URL] There are a number of existing scripts which might be helpful in offering solutions to how this can be achieved - e.g. [login to view URL] or [login to view URL] I don't need to save the actual Google Books images - just the URLs which point to the pages within the book.
