HOF is all about knowing how functions are able to intertwine and use information from each other. As an experienced programmer we'll all want the ability to be able to know how to call on other functions, modify them, and use them as inputs for other functions.

Modules can be described as being a file containing a set of code or functions that are then imported to your application for use. It's like separating all the functions to be in one organised file so that you can use those function through the main base of your code. Here is what I have learnt on day 12 about what we can achieve with them.

List comprehension took me a while to get used to, lambda functions more. Both serve to make Pythonic code simpler and easier. Knowing these functions helps to build more efficient code. Here's what I’ve learnt...

Earlier in this series, I learned about built-in functions, which are pre-built and used throughout Python code. When creating code, we need to be able to define our own functions.
