Python Decorators 101 Christopher Bailey 00:56

This video concludes the section on Python functions and gives you a review of what has been covered up to this point. Here’s what you learned so far:

Functions can return a value based on their given arguments
Functions are first class objects and they can be accessed inside lists or dictionaries
How do define functions inside of other functions
How to call and return inner functions

Now that you understand how functions work in Python, you’re ready to learn more about decorators.

00:00 Up to this point, we’ve been focusing on functions. You started out defining a function—talking about the header, the statement, and calling the function.

00:10 We discussed how a function returns a value based upon its given arguments.

00:18 Then, I showed you how functions are first-class objects. They can be accessed inside of a list or a dictionary.

00:27 That inside of Python, they have a lot of the same properties as other objects. Next, I showed you how you could define functions inside of functions, and how they can be called inside of that function themselves.

00:40 And the last thing that I covered with you was how you could return a function from within a function so that you can access them outside the local scope.

00:50 Congratulations. With all that background covered, you’re ready to talk about decorators.
