I'd be happy to help you with that!
Commenting in Python is essential for making your code readable and understandable by others (or yourself, after some time has passed). There are a few different ways to add comments in Python:
Line Comments
You can add a comment on any line of your code using the # symbol. Any text after the # will be considered as a comment.
Example:
print("Hello, World!") # This is an example of a line comment
In this example, the text "This is an example of a line comment" is just for humans reading the code and will not affect how the program runs.
Block Comments
You can also use triple quotes (""") to create block comments. Any text between these three double quotes (or single quotes) will be considered as a comment, until the next set of three double quotes or single quotes.
Example:
"""
This is an example of a block comment that spans multiple lines.
It's useful for explaining complex code sections!
"""
In this example, any text between these three double quotes (""") will be ignored by the Python interpreter. This is especially helpful when you have long explanations or notes that need to accompany specific parts of your code.
Docstrings
Python has a special type of comment called a docstring (short for "documentation string"). Docstrings are used to document functions, classes, and modules. They provide information about what these code constructs do and how they should be used.
Example:
def print_hello_world():
"""
Prints "Hello, World!" to the console.
Parameters: None
Returns: None
"""
print("Hello, World!")
In this example, the docstring provides information about what the print_hello_world function does, its parameters, and what it returns. This can be helpful when others are using or maintaining your code.
Best Practices
When commenting in Python (or any programming language), keep the following best practices in mind:
Be clear and concise in your comments. Explain why something is being done, not just what. Use meaningful names for variables, functions, and classes to make your code self-documenting. Avoid repeating information that's already obvious from reading the code itself.I hope this helps you understand how to comment effectively in Python!

W3Schools Python Comment Example
This is an example of commenting code using
Python's triple quotes and hashtags.
Using triple quotes to comment out a block of code.
"""
This will be commented out because it starts
with three quote marks and ends with three
quote marks, like this """.
Using the hash symbol (#) for line comments.
This is just one way you can comment your Python code.
