How to Write Cleaner, Smarter Code

In partnership with

Writing good Python code is not just about making it work. It is about making it easy to understand, maintain, and improve. One of the simplest but most powerful tools for that? Well-placed, smart comments.

This week, we’re looking at how to write cleaner, smarter code using comments. That includes when to use them, how to make them effective, and when to leave them out.

In Python, as with many languages, comments start with a # symbol. Anything after the # on that line is ignored by the Python interpreter.

# This function adds two numbers
def add(a, b):
    return a + b

We use it all the time in our demos. Read the full guide to Python comments to get the best practices.

He’s already IPO’d once – this time’s different

Spencer Rascoff grew Zillow from seed to IPO. But everyday investors couldn’t join until then, missing early gains. So he did things differently with Pacaso.
