Intermediate Python

Python is a programming language that is used for a variety of different web applications. In this Intermediate Python learning Track, you'll take your Python skillset to the next level.

For this Track, the recommended prerequisite is our Beginning Python Track.

While basic Python has many useful applications, intermediate Python is your key to progressing into more advanced work with data, machine learning, programming, and much more.

This Track starts with a Python File I/O course—mastering the re module that Python provides will help you read and write data to and from files, as well as write regular expressions for many different situations.

Next, you'll learn CSV and JSON for Python. CSV and JSON files are two very common formats for storing and retrieving data, and are an important building block for intermediate Python.

Database interaction is often an important part of Python work—you'll explore it in this Track with the ORM Peewee. In this databases course, you'll build a command line diary application that puts your thoughts and notes into a SQLite database, lets you review and delete them, and has a search feature.

Next up is Python Testing and Python Comprehensions, respectively. In the Testing course, you'll cover doctests, Python's unit test library, and the third-party package The Comprehensions course teaches you what you'll need in order to skip the for loop and start creating lists, dicts, and sets straight from your iterables. You'll also learn how to use comprehensions to emulate things like map() and filter() in an easier way.

The next course in the Track is Python Decorators—you'll how to construct your own decorators and learn the ways Python handles functions, scope, and closures. Python Type Hinting is next up—the Python versions 3.0, 3.5, and 3.6 all use type hints, and you'll learn all about them.

Finally, to wrap up the Intermediate Python Track, you'll cover Functional Python. Functional programming in Python allows you to quickly filter lists, modify values, find answers, and other tasks with a clean, minimal approach.

Take your programming skills to new heights with this Intermediate Python Track!
