Yes! Indentation, or leading white space at the beginning of a line is required in Python. You can read more about why that is important here. And here is the part of the style guide convention for indentation (PEP 8).

Python has three similar data structures that can hold an unordered collection of elements: list, tuple and set.

In a large web application, the backend logs can get quite verbose: requests created, sent, processed, received, etc. The list can grow large very quickly depending on how logs are implemented.

TL;DR: This is a very good book. If you are a software developer I highly recommend it!

My primary debugging tool is to add print statements to my programs</confession_time>. Print statements are very easy to use and they work well for any simple scripts. But that’s the catch: if you’re debugging an application and/or a test file, print statements won’t be enough or will just not work (in the case if tests files).
