I'm reading this online material about Python, a programming language, and I can't understand a paragraph in it. Please don't worry if you don't know what Python is, because I believe this very quotation has nothing to do with coding:
Q: Are you sure # is called the pound character?
A: I call it the octothorpe because that is the only name that no country uses and that works in every country. Every country thinks its name for this one character is both the most important way to do it and the only way it's done. To me this is simply arrogance and, really, y'all should just chill out and focus on more important things like learning to code.
My question is: What does the author mean by saying "that is the only name that no country uses and that works in every country"?
