j: I just love this about working in Jupyter notebooks! It’s so easy to gradually build what I want, and check my work every step of the way. I make a lot of mistakes, so this is really helpful to me…
Often when we download files from the internet, there are a few that are corrupt. Let’s check:
failed = verify_images(fns)
