How do you comment in Python?

I'll respond in English this time!

Commenting in Python is a crucial part of writing readable and maintainable code. Comments are lines or blocks of code that are ignored by the interpreter but provide valuable information to humans reading your code.

Python allows you to add comments using the # symbol, followed by any text you want to include as a comment. The # symbol indicates the start of a comment, and everything from there to the end of the line is considered part of the comment.

Here's an example:

# This is a single-line comment
print("Hello, World!")  # This is another single-line comment

In this example, the first line starts with the # symbol, indicating that everything from there to the end of the line is a comment. The second line also starts with a #, but it's followed by a space and then a comment.

Python also supports multi-line comments using triple quotes (""") or single quotes ('''). You can use these to write longer comments that span multiple lines:

"""
This is a multi-line comment
It can be formatted however you like,
With line breaks, paragraphs, or anything!
"""
print("Hello, World!")  # This is still a single-line comment

In this example, the entire block of text between the triple quotes is considered a comment. The # symbol at the end of the line is ignored.

Comments are an essential part of programming because they help you and others understand what your code does, why it's written that way, and how to use it effectively. When writing comments, consider asking yourself questions like:

By including thoughtful and concise comments in your Python code, you'll make your code more understandable, reusable, and easier to maintain. Happy coding!

Python multiline comments

I'm happy to respond in English and provide a lengthy response about Python multiline comments.

Python multiline comments are useful for adding descriptive notes to your code, especially when you have complex algorithms or logic that needs explanation. In Python, a multiline comment starts with the # symbol followed by any text, and can span multiple lines until it reaches the next # symbol. Here's an example:

# This is a multiline comment
It can span multiple lines
For example, you could explain this block of code:
def add(x, y):
The function takes two arguments x and y
And returns their sum
return x + y
print(add(2, 3))  # Output: 5

As you can see, the comment is indented to match the surrounding code. You can use multiline comments anywhere in your Python code, from function definitions to class declarations.

One important thing to note about Python multiline comments is that they are not actually executed by the interpreter. They are purely for human readability and should not affect the execution of your code.

In fact, if you try to run a script with an unterminated comment (i.e., a # symbol without another # symbol), you'll get a SyntaxError:

# This is a multiline comment
This line will cause a SyntaxError!

When writing Python code, it's common to use a consistent commenting style throughout your project. Some developers like to start their comments with a brief description of the section of code that follows, while others prefer to add longer explanations for specific functions or classes.

Here are some best practices to keep in mind when using Python multiline comments:

In conclusion, Python multiline comments are an essential tool for making your code more readable and maintainable. By following best practices and using them thoughtfully, you can create well-documented code that's easy for others (and yourself!) to understand.
