This video concludes Section 2 on Decorators. You now know how to:

  • Create simple decorators and apply them to functions
  • Apply syntactic sugar by using the @ symbol to decorate your functions
  • Reuse decorators and import them in your programs
  • Decorate functions with arguments
  • Return values from decorated functions
  • Perform introspection on Python objects and how to use functools

In the next section, you’ll cover a few real world examples.

00:00 Congratulations on finishing Section 2! By using the information that you learned in Section 1, you are ready to start using decorators. I showed you some simple decorators and how to apply them to your functions.

00:15 Next up, you learned how to apply a little bit of syntactic sugar by using the at symbol (@) to decorate your functions as you define them, or even after you define them. After that, it was all about reusing decorators on multiple functions. Here, you saved your decorators in a module that could be imported and used at any time.

00:37 And then you covered what you need to be aware of when you’re decorating functions that have arguments. And I discussed with you *args and **kwargs—positional arguments and keyword arguments. Next, now that you’ve passed information into a function, you covered how to return values from your decorated functions.

01:02 And last, you talked about introspection,

01:07 and “Who are these functions, really?” and how to use functools. Great! Now you’re ready to look at a few real-world examples in Section 3.

01:18 See you there!
