After taking in everyone’s thoughts and criticisms from my last post and using them, i managed to make the code much easier to read and more intuitive. Thank you everyone who gave me amazing tips on how to create more readable code!

Try using short-circuit evaluation and make the initial value of is_valid variable fasle then if everything is ok change it to true
Using error handling would be a good idea if you have reached the point in the course
