Python is a powerful programming language with rich annotation functions. I believe that most developers know the importance of adding comments when writing code. Not only does it help code maintenance and increase code readability, but it also makes it easier for other developers to understand and modify the code. However, due to the flexibility of the syntax, there may be many unstandardized annotation errors in Python. In this article, we will introduce how to solve Python's comment irregularity error.

1. Use of comment symbols

In Python, comment lines usually start with the # sign. When writing comments, you should ensure that the comment symbol is immediately after the #, which is the recommended practice in the official Python documentation. For example: # This is a comment, not # This is a comment.

In addition, there is a multi-line comment method in Python - a comment block formed by three quotation marks. When writing such comments, care should be taken to distinguish the quotation marks within the comment block from the quotation marks of the current code. The following is an example of a comment block:

"""
This is
a multi-line
comment
"""

2. Position of the comment

In Python, comments should be immediately above or to the right of the commented code. If the annotation is too far away from the annotated code, it may have a negative impact on code readability. Here are some examples of comment positions:

This is a suitable comment position

x = 5 # This is also a suitable comment position

This is an inappropriate comment position

Because it is too far away from the commented code

3. Accuracy of comment content

Correct comments should clearly describe the function of the code and provide sufficient contextual information to help other Developers understand code. The accuracy of comments is related to the correctness and readability of the code, and comments should not be made just for the sake of comments.

If the content of the comments is incorrect or outdated, it will have a negative impact on the readability of the code and affect developers' ability to understand and modify the code. It may even cause the wrong code to be executed, causing serious consequences.

4. Chinese language of comments

If your code needs to be written in Chinese for special reasons, please be sure to follow the following specifications:

1. Use unified translation specifications , for example, some specific terms should be translated into corresponding Chinese vocabulary;
2. Avoid overuse or misuse of Chinese punctuation marks;
3. Pay attention to grammar and word order to avoid inaccurate translation or unclear semantics .

In short, in order to maintain the readability and correctness of Python code, comment standardization is crucial. When we write Python code, we should carefully consider its comments and avoid the mistakes of irregular comments.
