This highly interactive and advanced course will give you insight into the most common Python tricks and tips. This course is for practicing Python programmers who are aiming for proficiency in Python 3. If you want to switch from Python 2 to Python 3, this is your go-to course. 

This course will help you learn the Pythonic Way of writing code and leveraging advanced robust features to become more proficient than the average developer. You’ll start by covering Python’s built-in data structures, and then you’ll move on to different programming paradigms like functional programming and object-oriented programming. 

In the latter half of the course, you’ll focus on iterables, generators, and coroutines. You’ll also have the opportunity to work on two projects to help strengthen what you learn. In all, this course is perfect for anyone who wants to become a confident and competent Pythonista by picking up the idioms and practical tips.

Mastering the Art of Programming in Python 3

In the [beginning](https://www.educative.io/courses/mastering-the-art-of-programming-in-python-3/first-class-functions) of this chapter, we covered in detail that functions are objects, but the reverse isn't true. Not every object is a function, but Python allows us to use _callable_ objects. It means that an object can behave like a function. Let us dive into the details to see how this is possible. 
# Callable objects
The __callable__ objects are the objects that can be called like a function (using `()`), and can be passed as an argument in a function call. This is made possible with the `__call__` method. Look at the following example to see how to define a callable object.
