Functions are a programmer’s means of fulfilling the Don’t Repeat Yourself (DRY) principle, arguably the golden rule of programming. Functions allow us to write a piece of code once and use it multiple times in a piece of code with a single-line reference, a process called abstraction. In addition, we can use arguments to take in values and objects to use in the function, and return statements to bring objects back to the main body code. In Python’s object-oriented landscape, even the functions themselves are objects!
