What's the logic of having to import "math" before being able to use the functions? Are they not readily available?

If we don't import math, it looks like it becomes an undefined value.. but what is the benefit of having that vs having all of these functions 'pre-loaded'? Thanks!

Hi, Alexis Suberville! The math library is part of the base Python language, yes. But it is abstracted out into its own library. To use any of the libraries you need to import them. Math is just one of those. There are many many more including libraries to read CSV files, do basic statistics, handle data persistence, data compression and more. Your simple script would be incredibly bloated with unnecessary overhead if every library were loaded.

Here is a list of built-in libraries

Hope this helps! :sparkles:
