This is a question about how to comment out code in Python.
“how to comment out a block of code in python pycharm” is a question that was asked on the Tech Support Whale website. The answer given by the site, recommends using “commenting out” and “uncommenting” as methods for commenting and uncommenting code.
If you’re a Python developer, this article will show you “How to comment out a block of code in Python?” as well as the many forms of comments in any programming language.
In a programming language, what are comments?
If you’re a programmer or know how to use a programming language, you’re probably aware of how important comments are in programming. While compiling and executing the code, the compiler may skip a piece of the code using comments that can span many lines, a portion of a single line, or a whole line.
You may also use comments to add information about a function, a section of code, or a program block in the code. This enhances code readability.
What is the difference between a line and a block comment?
To explain the distinction between line and block comments in programming language, we’ll use a simple Java program as an example.
1. Comment on the first line:
Use two forward slashes’ / at the beginning of the line you wish to comment out, as illustrated below. The compiler will bypass this commented line when building and running the code.
The following is the output of the aforesaid program:

2. Add a comment block:
If you wish to comment out numerous lines or a block of code, use forward slashes / in front of each line of the block code, as mentioned above. However, if there are more lines, commenting each one will be time-consuming and annoying. You may use block comment to comment out a section of the code in this case.
By inserting /* at the beginning of the first line and */ at the end of the final line, you may comment out a block of code.
The following is the output of the aforesaid program:

In Python, how can I add a line comment and a block comment?
Python line comment:
At comment a line of code in Python, add #(hash) to the beginning of the line, as seen below.
The above program’s output will be

Python block comment:
Block comments are not supported in Python. In Python, you can’t comment out a section of code. If you wish to comment out numerous lines of code, put #(hash) at the beginning of each line of code. Yes, most Python coders are familiar with this being the sole method to comment out a section of code.
Some editors allow you to add #(hash) at the beginning of selected lines using a menu or shortcut key. Depending on the IDE you’re using, you’ll have different choices or shortcut keys.

Another technique to comment out a section of code in Python is to:
Do you want to know whether there’s another method to get block comments in Python? Yes, it is correct.
In Python, you may comment out a piece of code using multiline-strings. Source code is not generated by multiline-strings. As a result, code contained inside a multiline-string is treated as a string and is skipped during execution.
You may quickly remark numerous lines of code by adding “”” at the beginning and end of the block of code.
The following is an example of how to utilize a multiline string for commenting.
Note: In Python, you may add block comments by using multiline-strings, however this is not a good style of coding. We’ve heard of Python programmers having issues utilizing multiline-string to comment out blocks of code. We don’t suggest this method as a good practice.
Conclusion:
We hope this post was helpful and that you now have a better understanding of block comments in Python. To summarize, instead of using multiline-string to comment out a block of code in Python, use #(hash).
If you have a different method that you utilize as a best practice, please share it in the comments area to benefit other developers.
Cheers!!!
