Want to start learning Python but struggling to find quality resources? Well, they're out there—and we'll review them here. In no particular order, here are the best online resources to learn Python.

Courses

1. Vertabelo Academy

Vertabelo Academy is an interactive e-learning platform that offers nine Python courses. Among them, you can find two learning paths: programming and data science.

Programming path:

• Python Basics Part 1. This is the first of a two-part course that covers everything you need to know about Python so you can start writing your own scripts and applications. You’ll learn how to use variables, data types, mathematical operators, conditional statements, loops, and functions.
• Python Basics Part 2. Building on the first course in the series, this Python course reviews important issues related to data structures: lists, dictionaries, error handling, processing user input, and operating on text files. You’ll learn to write more complex applications and create scripts to automate various tasks.
• Python Basics Part 3. This is the final course in our Python Basics series. You'll learn new powerful data structures: tuples and sets. Together with lists and dictionaries, they comprise the essential data structures that any aspiring Python developer should know. You’ll also learn how to work with date and time. Once you finish these three basic courses, you’ll be able to write advanced applications that solve a variety of problems commonly found in the IT world.
• How to Read and Write JSON Files in Python. If you know the basics of Python, you can take this course to learn more about processing files. This includes opening, reading, and processing JSON files. You will learn how to handle JSON files with NULL, arrays, or nested objects. You will also learn how to differentiate JSON and CSV files. This is a great guide for students, beginner developers, and programmers.
• Python Data Structures in Practice. This is a good course for beginner programmers or students with basic Python skills who want to gain practical knowledge of Python and learn how to solve fundamental programming problems with basic data structures. You will analyze common cases for each of the four data structures and present optimal solutions to typical problems. At the and of this course, you have the chance to write a PC game.
• Built-in Algorithms in Python. This course is the next step after the “Python Data Structures in Practice” course. You will learn how to apply typical operations to basic data structures, like finding the highest value in the dictionary, sorting string values in a list, or checking if tuples contain a given element. This course answers questions about searching, sorting, using the “in” operator, and finding the index of elements in a given structure or the number of occurrences of an item. You will also learn how to apply lambdas. This course is not only for junior programmers but also for professionals who use Python.

Data science path:

• Introduction to Python for Data Science. This course is ideal for anyone who wants to specifically use Python for data analysis. You’ll learn how to import and work with CSV files, create simple data visualizations, perform simple data analysis, and work with variables, data frames, and filters. You’ll also gain hands-on experience with Python data science libraries such as matplotlib for data visualization and pandas for data analysis.
• Working with Strings in Python. This course extends your knowledge about string operations in Python, which are widely used in all modern programming languages. You'll learn how to join, slice, and iterate over strings and will explore string functions such as replace(), split(), and strip(). You’ll also learn how to format and display string values. This course is perfect for students who have very basic knowledge of Python.
• How to Read and Write CSV Files in Python. This introductory course teaches you how to operate on data from a CSV file. You’ll learn how to read CSV files with opencsv, process them in for loops, read a CSV row into a list or dictionary, and switch between various CSV formats. This course also teaches you how to create a custom CSV dialect that matches your preferred CSV file format. This course is recommended for students with basic Python skills.

All these courses are designed with beginners in mind, so if you don’t have any programming or IT experience, you’ll feel right at home. You don’t even need to know how to install Python or set up an interactive development environment (IDE)—you can get your hands dirty in Vertabelo Academy’s sandbox environment.

Experienced software developers will tell you that the best way to learn programming is by doing— and that’s exactly what you get with Vertabelo Academy. In each course, you’ll gain hands-on practice with plenty of interactive exercises, and you’ll get real-time feedback on your work. If you have any questions, you can also chat with other members of the Vertabelo Academy community in the Discuss tab of the course.

Getting started with Vertabelo Academy is rather straightforward: you just need to register with your email address or social media profile (Facebook, Google+, Twitter, or GitHub) and then purchase a course. You can also take advantage of course bundles to save money.

At the end of every course, you’ll get a verifiable certificate of completion to showcase your mastery. And if you’re not satisfied with the quality of a course, you can get a refund within 30 days of purchase.
