🐍 Python Basics: Understanding Comments

1. What Are Comments?

A comment is a line of text in your code that Python ignores when executing the program. Comments are used to add explanations, make notes, or temporarily disable parts of the code.

2. Single-Line Comments

In Python, you create a single-line comment by using the # symbol. Anything after # on that line is ignored by Python.

Python will execute the print() function but ignore the comments.

3. Multi-Line Comments (Using Multiple #)

Python doesn't have built-in multi-line comment syntax, but you can create them by using multiple # symbols:

This is a common way to write longer explanations in Python.

4. Multi-Line Strings as Comments

Another way to write multi-line comments is by using triple quotes """ or '''). Technically, these are multi-line strings, but when not assigned to a variable, Python ignores them.

This method is often used for docstrings (which we’ll cover next).

5. Docstrings: Special Comments for Documentation

A docstring is a special type of multi-line comment used to describe modules, functions, and classes.

You can access a function’s docstring using:

Output:

This function prints a greeting message.

6. Why Use Comments?

✅ Improve Code Readability – Explain what complex parts of your code do.

✅ Make Maintenance Easier – Help future developers (or your future self) understand the code.

✅ Debugging – Temporarily disable parts of your code using comments.

Bad Example:

Better Example:

Use comments wisely—don't overdo them!

🏆 Conclusion

Comments are a powerful tool in Python that help you write clearer, more maintainable code. Use them to explain why your code does something, not just what it does.
