The common header format of Python files is a simple yet essential element in any Python script. As you will see, the header format is like the introduction to a beautiful piece of prose—it sets the stage for what's to come and provides valuable context. In Python, we commonly use a docstring as the header format. A docstring is a special kind of comment enclosed within triple quotes either single or double. It's placed right at the beginning of the script, even before any import statements, making it easily visible and accessible to anyone who reads the code. The standard structure of a Python file header, adorned with a docstring, looks something like this:. File:: Here, we include the name of the Python file, like filename.

There are many resources that teach you how to write code, but when it comes to writing clean and readable code, many beginners are unaware of the principles and techniques. In this article we'll explore how to write Python headers, one of many things that can level up the readability of your code. In general, file headers are blocks of information - often positioned at the top of the file - that contain metadata about the file and its content. Similar to this, a Python Header consists of a shebang and a docstring present at the top of the file that provides more information about the file and the code present inside it. As mentioned, headers provide metadata about the file that can help understand the context as well as track the changes in the file. It not only helps the readers, but the developers to get up to speed quickly with the context. You might see something like!

This document gives coding conventions for the Python code comprising the standard library in the main Python distribution. Please see the companion informational PEP describing style guidelines for the C code in the C implementation of Python 1. This style guide evolves over time as additional conventions are identified and past conventions are rendered obsolete by changes in the language itself. Many projects have their own coding style guidelines. In the event of any conflicts, such project-specific guides take precedence for that project.

In Python code, it is permissible to break before or after a binary operator, as long as the convention is consistent locally. Sign up for free to join this conversation on GitHub.

After initialization, Python programs can modify sys. Learn more about clone URLs. Comments that contradict the code are worse than no comments. Each module has its own private namespace, which is used as the global namespace by all functions defined in the module. Released: Sep 18, This will ensure that concatenation occurs in linear time across various implementations. Imported names should always be considered an implementation detail. With the acceptance of PEP , the style rules for function annotations have changed.

Now that we've learned the utility and functionality of Python file headers, let's delve deeper by using several examples and their explanations to further explore the world of header format in Python. Thanks for sharing! For clarity, it is recommended to surround the latter in technically redundant parentheses:.
