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 Congratulations on reaching the end of this Python Basics Exercises course. You’ve completed a total of ten exercises that tested your knowledge of working with numbers in Python. More specifically, you’ve practiced using integer and floating-point literals to define numbers in Python; the format specification mini-language to control how numbers are displayed; numbers supplied by the user, which require a type conversion to be processed correctly; and finally, math functions and number methods to perform calculations.

00:34 Along the way, you picked up a few useful tips that may help you tackle exercises like these in the future or solve actual programming problems that you might come across at work.

00:45 It’s always a good idea to read the instructions carefully to make sure that you understand the problem correctly. Apply the divide-and-conquer principle to break a big problem into smaller tasks that are more manageable and easier to solve.

00:59 Take your time to think through the problem and come up with a plan before writing any code. It can spare you from implementing something that you wouldn’t need at all.

01:08 When writing code, take small steps to help you focus on one little task at a time. Keep your code clean and easy to follow by giving variables descriptive and meaningful names.

01:20 It will help you and others understand the code more quickly. Occasionally, you can use comments to explain difficult or surprising fragments of code. Try to explain why rather than the what. Last but not least, validate each step as you go. In the long run, this approach can reduce the time you’ll spend debugging your code when it stops working as expected. Before closing this course, have a look at a few additional resources available on Real Python, which you can check out as a follow-up to learn even more about working with numbers in Python.

01:56 Bear in mind that some of these are advanced tutorials that may require a bit more Python experience before diving in. As always, the slides for this course are available for download in the supporting material dropdown below this video.
