If you’re just getting started with learning Python, you may be wondering how to make comments in your code. This brief tutorial will show you how to do just that!

In computer programming, a comment is a programmer-readable explanation or annotation in the source code of a computer program. Comments are added with the purpose of making the source code easier to understand for humans reading it. In Python, comments start with the pound (#) sign and are single-line comments.
Multi-line comments are denoted by triple quotation marks (“””) and can span multiple lines. Anything following the triple quotation marks is part of the comment and will be ignored by the Python interpreter:
What are comments in Python?
In Python, comments are lines that exist in computer code, but are not read by the compiler and have no effect on the running of the code. They start with a # symbol and can be used to write explanatory text or insert temporary “TODO” notes into code.
How to make comments in Python?
In Python, comments are lines that are not executed as part of the code. They are used to explain what the code does and how it works. Comments start with the “#” character and continue until the end of the line.
What are the benefits of commenting in Python?
Comments are lines in a computer program that are not executed as part of the program’s code. They exist solely for the benefit of the programmer or anyone reading the code. In Python, comments start with a pound sign (#) and they are generally used to explain what a particular section of code does.
There are several benefits to commenting your code:
1. Comments can make your code easier to understand, both for yourself and for others who may need to read or work with your code.
2. Comments can help you debug your code by providing helpful reminders or explanations of what certain lines of code do.
3. Comments can make your code more modular and reusable by allowing you to include information about how different pieces of your code fit together.
4. In some cases, comments can improve the performance of your code by providing hints to the Python interpreter about how your code should be executed.
How to use comments to improve your Python code?
Comments are lines in your code that are not executed by the interpreter. They are there for you (and other people who may read your code) to understand what is going on. In Python, comments start with a #, and anything after that # is ignored by the interpreter.
For example, let’s say you have a program that prints “Hello, world!” to the screen. You could write it like this:
But if you wanted to add a comment to explain what the code does, you could write it like this:
# This code prints “Hello, world!” to the screen.
How to format comments in Python?
Most software developers recognize the importance of comments. Comments are lines of text within computer programs that are not executed when the program is run. In Python, comments start with a # symbol and they are used to explain what a given section of code does.
Comments can be placed at the beginning of a line or after code on the same line. For example, the following two lines are equivalent:
# This is a comment
print(“Hello, world!”) # This is also a comment
Comments can also span multiple lines. To write a multiline comment in Python, use the “#” symbol at the beginning of each line:
# This is a
# multiline comment
What are the best practices for commenting in Python?
There is no single answer to this question as commenting practices will vary depending on the individual programmer’s preferences and the specific project requirements. However, there are some general guidelines that most programmers agree on when it comes to commenting in Python.
One of the most important things to keep in mind when commenting is to make sure that your comments are clear and concise. It is also important to use comments sparingly, as too many comments can clutter up your code and make it more difficult to read.
In terms of specific style recommendations, it is generally agreed that Pythoncomments should be prefixed with a # character and that they should be placed on separate lines from the code they are referring to. Additionally, it is generally considered good practice to use inline comments sparingly and to reserve them for cases where a short explanation would be helpful.
Finally, remember that comments are for humans, not for machines. As such, they should be written in clear, concise language that can be easily understood by anyone who reads them. With these guidelines in mind, you should be able to write comments that are both informative and easy to read.
How to comment out code in Python?
In Python, comments are used to explain what a particular piece of code does. They are also used to prevent code from being executed. Comments begin with a # symbol and everything after the # is ignored by the Python interpreter.
For example, if you wanted to comment out a block of code that prints “Hello, world!”, you would write:
# print(“Hello, world!”)
Any code that is on the same line as a comment will also be ignored.
How to comment multiple lines of code in Python?
There are a few ways to comment out multiple lines of code in Python.
One way is to use the # character at the beginning of each line:
# This is a single-line comment.
# This is a second single-line comment.
You can also use multiple # characters:
#### This is a four-line comment. ######
Another way to comment out multiple lines of code is to use triple quotes:
”’This is a
In conclusion, adding comments to your Python code is a good way to improve its readability and make it easier for others to understand. When writing comments, be sure to use clear and concise language, and always remember that less is more.
