Mastering Multi-Line Comments in Python: A Guide to Efficient Code Organization

Learn how to efficiently comment multiple lines in Python using the # symbol and the docstring. Improve your code readability and organization with these simple yet powerful techniques.

Updated October 18, 2023

In any programming language, commenting your code is essential to make it readable and understandable for others. Python is no exception. In this article, we’ll explore how to comment multiple lines in Python, using both single-line and multi-line comments.

Single-Line Comments

Python uses the # symbol to indicate a single-line comment. Any text following the # symbol will be ignored by the compiler and not be executed. Here’s an example:

# This is a single-line comment
print("Hello, world!")  # This will be printed to the console

As you can see, the line starting with # will not be executed, and instead, the text following it will be printed to the console.

Multi-Line Comments

Python also supports multi-line comments, which are indicated by the --> symbol. Any text between the --> symbols will be ignored by the compiler, and can span multiple lines. Here’s an example:

---

This is a multi-line comment

print("Hello, world!")  # This will be printed to the console

In this example, the multi-line comment spans two lines, and anything between the --> symbols will not be executed.

Combining Single-Line and Multi-Line Comments

You can also combine single-line and multi-line comments to create more complex comments. Here’s an example:

# This is a single-line comment

---

This is a multi-line comment

print("Hello, world!")  # This will be printed to the console

In this example, we have a single-line comment followed by a multi-line comment. The single-line comment will not be executed, while the multi-line comment will be ignored.

Conclusion

In this article, we’ve covered how to comment multiple lines in Python using both single-line and multi-line comments. Commenting your code is an essential part of programming, as it makes your code more readable and understandable for others. By mastering the different types of comments available in Python, you can improve your coding skills and write more effective and maintainable code.
