Comments with # in Python

Python does not need to run every line you write. Some lines are just for humans, and that is where comments come in. This Block introduces comments with #: how Python ignores them, how they help readers understand your code, and how to use them without changing what your program prints.

What you will learn:

• Write comments with #
• Understand that comments are ignored by Python
• Add comments above code and beside code
• Spot the difference between a real comment and # inside text
• Use comments to temporarily disable lines of code
• Write helpful comments that explain intent instead of repeating the obvious

A small beginner skill, but a very useful one. By the end, your code will be easier to read without changing what it does.
