Import Order: A Matter of Readability and Maintainability

Does import Really Matter

Import order is a matter of style in Python, React JS, and other programming languages and developers often debate whether it actually matters or not. Some argue that keeping imports organized and sorted makes the code easier to read and maintain. Others argue that it is a matter of personal preference and has no impact on the functionality of the code.

On the one hand, having a clear and consistent import order can improve the readability of the code. When all imports are grouped together and sorted in a standard way, it becomes easier for developers to quickly scan the imports and understand the code's dependencies. This can be especially helpful when working on a large project with many different modules and dependencies.

However, it is imperative to note that the order of imports has no impact on the code’s functionality. The Code Editor or IDE will import modules in the order specified, but it will only import each module once, regardless of the order in which they are listed.

Style Guide

In terms of best practices, the Python style guide (PEP 8) recommends keeping imports at the top of the file, after any module-level docstrings, and before any other code. Imports should be grouped in the following order:

• Standard library imports
• Third-party library imports
• Local application/library-specific imports

Note: The Python style guide (PEP 8) recommends putting a blank line after each import group for readability.

Additionally, within each group, all imports should be sorted alphabetically by module name.

*In conclusion;* while the order of imports does not impact the functionality of the code, having a clear and consistent import order can improve the readability and maintainability of the code. Following the Python style guide recommendations is a reliable starting point for organizing imports in a way that is both readable and maintainable. Ultimately, the choice of import order is a matter of personal preference and may vary based on the specific requirements of a project.
