How Should You Structure a Python Project for Maximum Efficiency and Maintainability?

Exploring Project Structure Options for Comprehensive Python Applications

Considering the development of a Python application beyond its basic form, selecting the ideal project structure is crucial. This decision underlies essential factors such as maintenance efficiency, IDE compatibility, version control management, and packaging for distribution.

Establishing a Project Hierarchy

While project structure in Python is relatively flexible, certain directory conventions contribute to project organization.

• Source Code: Centrally locate the application's source code in a dedicated directory, typically named "src" or "code".
• Startup Scripts: Store scripts necessary for application initialization in a directory such as "bin" or "scripts".
• IDE Configuration: Isolate IDE-specific project settings and configuration in a separate directory. This prevents unwanted version control clutter.
• Tests: Segregate unit and acceptance tests into a dedicated "tests" directory.
• Non-Python Data: Place non-Python data, such as configuration files, in a separate directory like "data" or "config".
• Non-Python Sources: Any non-Python sources, such as C extensions for binary modules, should be placed in a distinct directory like "lib".

Additional Considerations

• /src Directory: While some argue that the /src directory is unnecessary in Python projects, others prefer its use for organizing source code.
• Top-Level Directory: The top-level directory can reflect the application's architecture, potentially including directories for different modules or components.
• Version Control: Maintain a central repository and establish branching and merging workflows to facilitate collaboration.
• Package Distribution: Consider the requirement for creating executable packages for distribution, ensuring easy deployment.
