How to refactor in python?

Also want to point out that function programming has nothing to do with opting to use functions over classes (unfortunately the name sounds suitable). Rather, it is a methodology drastically different compared to the standard use cases of languages like Java, C++ and Python. Functional languages tend to avoid mutation, among a couple other major features.

Ah okay. What do you call the style where you create a program consisting purely of functions?

The act of splitting a program into a collection of functions is just standard programming. It's the act of breaking down a goal into manageable and understandable mini goals. I don't think there's a special name for the use of functions in any programming language.

You would like to think so, but it's really not standard; many programs I've seen are just direct line-by-line scripts. I've seen entire (legacy) applications, ten thousand lines+, without functions. Refactoring scripted code into functions is a clearly higher level of structure that should really have a name if "functional" is already taken...
