A problem with using print statements is it makes a mess of your code. IE, you have a function with 10 parts to it and you know it crashes somewhere, but you're not sure where. So you add in 10 extra print statements to pinpoint where the bug is. Once you've found and solved your bug, you now have to clean up by removing all of those print statements. Maybe you'll do that. Maybe you'll forget and it'll end up in production and your user's console will be full of debug prints.
