The Python range() Function: Recap

Austin Cepalia

The Python range() Function Austin Cepalia 01:15

You now understand how to use range() and work around its limitations. You also have an idea of how this important function has evolved between Python 2 and Python 3. The next time you need to perform an action a specific number of times, you’ll be all set to loop your heart out!

Congratulations, you made it to the end of the course! What’s your #1 takeaway or favorite thing you learned? How are you going to put your newfound skills to use? Leave a comment in the discussion section and let us know.

00:00 In this course, we saw how we can use Python’s range() function to generate lists of numbers to iterate over. We learned how to create lists of incrementing and decrementing numbers, how to reverse a list, and how to use this range() function alongside the for loop to perform some sort of operation on each value in our generated list.

00:26 We also saw some of the technical limitations behind generating floating-point values, and we learned how the range() function has evolved from Python 2 to Python 3, notably how range() has replaced xrange().

00:45 I hope you can see now why the range() function is so powerful. Whatever you are working on, you’re bound to run into a scenario where you need to iterate over a chunk of code x number of times, and you might even need to use that incrementing variable within your code.

01:04 The range() function makes all of this possible.
