In this section, we take a closer look at Python’s modules and import systems as they are the central elements to enforcing structure in your project. We then discuss various perspectives on how to build code which can be extended and tested reliably.

If your project is expressable as a single Python source file, then put it into the directory and name it something related to your project. For example, Twisted/twisted.py . If you need multiple source files, create a package instead ( Twisted/twisted/ , with an empty Twisted/twisted/__init__.py ) and place your source files in it.

You’ll see examples of common Python application structures, including command-line applications (CLI apps), one-off scripts, installable packages, and web application layouts with popular frameworks like Flask and Django.

Let's focus first on directory structure, file naming, and module organization. I recommend you to keep all your module files inside a src dir, and all tests living side by side with it: Top-Level project. Where <module> is your main module. If in doubt, consider what people would pip install and how you would like to import module.

Sep 1, 2019 · Option 1 (recommended): entry_point + console_scripts register a function in your project as the entry point to script execution (ie: proj:foo:cli:run). Option 2: scripts: Use this keyword argument in the setup() method to reference …

Jan 15, 2019 · Option 2: Python Script This is the method I'd recommend, as it's the most portable. Outside of your top-level package, you can write a separate Python script, such as run.py or cards98.py, and then use that to execute your main function. For example, in cards98/__main__.py, you can put this...

May 26, 2020 · In this article, I’ll show you three scripting conventions and corresponding built-in modules to help better format your Python scripts.

Jul 24, 2023 · Most modern projects adopt a “src” (source) directory to hold the main source code of the project. This provides a clean separation from configuration files, documentation, and other non-code...

That's where having an understanding of Python file and project directory structures comes in. In this article, we'll review some key concepts in structuring Python projects and how to best apply them.

Mar 10, 2025 · Let's explore some best practices for structuring Python projects. Most Python projects benefit from following a standardized structure: ├── conf.py. └── index.rst. Group related functionality together. Consider organizing your code into these common directories: The project root should contain only high-level files like:
