If you’re an experienced Python developer, these features may come in useful. If you’re totally new to Python and want to learn, swing by Python.org for its handy beginner’s guide to programming and Python. If you’re the kind of developer who learns best by watching videos, Microsoft’s video series, “Python for Beginners,” features dozens of short lessons (most under five minutes in length; none longer than 13 minutes) in the various aspects of Python.
Should you be the type who likes to pick up knowledge of new tools and languages via online learning portals, there are many Python tutorials out there, as well, including Datacamp (whose Introduction to Python course includes 11 videos and 57 exercises), Udemy (which offers a variety of free introduction courses, including one for “absolute beginners”), and Codecademy. As you build knowledge, don’t be afraid to head over to Stack Overflow to ask questions about things that might stump you.
And learning Python could prove vital to your career, as the language seems poised to continue its swift ascent. Earlier this year, SlashData’s State of the Developer Nation suggested that Python had the world’s second-largest programming-language community, at 10.1 million people. How long until it becomes the biggest?
