Treat this as a two part problem: part one is extracting the text; part two is parsing that text for your desired information. Unless you have a specific need for extracting the text with python, I’d recommend solving part one with an image-to-text reader. These have gotten really quite good recently (AI no doubt). Then parsing the text with python’s string handling routines should be pretty straightforward.
