Functions can also be reused, often they are included in modules. Related course: Complete Python Programming Course & Exercises. Example Functions
Functions are a convenient way to divide your code into useful blocks, allowing us to order our code, make it more readable, reuse it and save some time. Also functions are a key way to define interfaces so programmers can share their code. How do you write functions in Python? As we have seen on previous tutorials, Python makes use of blocks.
