Why does Python not have multiline comments?

Why does Python not have multiline comments?

I'd be happy to explain why Python doesn't have traditional multiline comments like other programming languages.

In Python, the primary goal is to keep the code concise and readable. The creators of the language aimed to make it easy for developers to write and understand code without getting bogged down in unnecessary verbosity. One way they achieved this was by using whitespace effectively.

Python's syntax allows you to use indentation (spaces or tabs) to define block-level structure, making it clear where certain blocks of code begin and end. This is particularly useful when working with loops, conditionals, functions, and classes.

Now, you might be thinking: "But what about comments? Don't we need them?" Indeed we do! Python provides a way to add comments using the # symbol followed by your comment text. This style of commenting is often referred to as "inline" or "single-line" comments.

The key thing to understand here is that Python's design emphasizes simplicity and readability over traditional multiline comments. By keeping your code concise and well-structured, you can reduce the need for long comments that might make the code harder to read. In other words, if your code is easy to understand, you won't need lengthy comments to explain it.

That being said, there are situations where you might want to use multiline comments in Python. For example, when working with large, complex systems, or when explaining code for others who might not be familiar with the project. In these cases, you can use multi-line string literals (triple quotes) to create a block comment that spans multiple lines.

Here's an example:

"""

This is a multiline comment

that spans multiple lines.

It helps explain what this code does.

"""

In summary, Python doesn't have traditional multiline comments because its design prioritizes readability and simplicity over verbosity. The language relies on whitespace to define block-level structure, making it easy to write and understand code without the need for lengthy comments. However, there are situations where you might want to use multi-line string literals to create a block comment that helps explain your code.

How to comment multiple lines in Python VSCode

I'm happy to help! However, I need to clarify that you requested a response in English, and I'll make sure to keep it that way.

Now, let's talk about commenting multiple lines in Python using VSCode!

When working with code editors like VSCode, commenting multiple lines is an essential skill. Here are a few methods to achieve this:

One of the most straightforward ways is to use triple quotation marks ("""). This allows you to comment multiple lines by simply enclosing them within these quotes.

For example:

# This will be commented out

"""

This line and all subsequent lines

will be ignored by Python's interpreter.

"""

To apply this method, just place your cursor at the beginning of the first line, type """, and VSCode will automatically highlight everything within these quotes as a single comment block.

The good ol' number sign (also known as the pound sign) is another way to comment multiple lines. You can place this symbol at the beginning of each line you want to comment out:

For example:

# This line will be ignored
And so will this one

However, keep in mind that VSCode might not automatically highlight these lines as a single comment block.

VSCode has built-in support for block commenting! You can use the Ctrl+Shift+K (Windows/Linux) or Cmd+Shift+K (Mac) keyboard shortcut to toggle the commenting of multiple lines:

This method works well for smaller code blocks, but if you need to comment a larger section, using triple quotation marks might be more convenient.

If you prefer a more streamlined experience, consider installing the Python Comment Blocker extension in VSCode! This plug-in provides an even faster way to comment and uncomment multiple lines:

Now you know four different methods to comment multiple lines in Python using VSCode! Try them out and find which one works best for your coding workflow.
