>Who writes python this way? No one, obviously. This is about understanding how the python interpreter functions. >Python has a rich library of string methods, maybe use them? How are you able to get the impression that any of this is a prescription on how python programming should be done? Nowhere does it claim to be, in fact if you read the actual content you would understand why these examples aren't the way to accomplish your goals. Why are you so incredibly defensive when someone points out that a programming language contains weird behavior most people do not understand? This is true for every language. And almost always these examples are given so that people can refine their understanding of the language. >Jeez. It's like me complaining that Rust looks ugly (it does). The language was designed with a different set of priorities. The only person complaining is you.
