When should I use functions or methods in programming?

When should I use functions or methods in programming?

You should use functions when you want to perform a specific task that can be reused, and methods when working with objects.

Can you give me an example of a function?

Sure! A simple function in Python could be def add(a, b): return a + b, which adds two numbers.

What about methods? How are they different?

Methods are functions that belong to an object. For example, list.append() is a method that adds an item to a list.

Are there any performance differences between using functions and methods?

Generally, the performance difference is negligible, but methods can have overhead due to object context.
