Python Functions Quiz Part-1

Check out this post, if you wish to test your comfort level with Python functions. They are one of the key ingredients of the Python programming ecosystem just like classes, exceptions, and file handling.

In this quiz, we’ve covered 20 basic questions on the Python functions. If you are a beginner, then this quiz could be a good medium to rehearse the concepts learned.

Most probably, you would know that every entity that holds or references to data or metadata is an object in Python.

And Functions in Python are also objects. This unique ability enables the programmers to leverage the full potential of functions.

If you want to excel in Python programming, then you must know how to optimize the code. We host a detailed guide on this blog that can help you learn optimization. Attempt the quiz and come back to read the below post.

Now, go through the below quiz and see how you score in this test.
