Using Comments in Databricks Notebook

In this post, you'll learn how to add comments in Databricks notebooks using different techniques.

🔹 What is a Comment?

A comment in PySpark (Databricks notebooks) is a line in the code that is ignored by the interpreter. It is used to:

• Explain the code for better readability.
• Temporarily disable code during debugging.
• Document the logic of the program.

🔹 Single-Line Comments

Use # to create a single-line comment.

# This is a single-line comment in PySpark print("Hello, World!") # This is an inline comment

🔹 Multi-Line Comments

You can use triple quotes ''' or """ to write multi-line comments or docstrings.

''' This is a multi-line comment. It spans multiple lines. ''' print("Hello, World!")

🔹 Shortcut in Databricks Notebook

For commenting multiple lines in a Databricks notebook:

• On Windows: Ctrl + /
• On Mac: Cmd + /

💡 Pro Tip: Use comments to explain complex code and improve collaboration with your team!
