Doxygen for Python How to generate documentation for nested functions

Doxygen is a powerful tool for documenting source code. While it's commonly associated with C++, it can also be used for Python projects. This tutorial will guide you through the process of generating documentation for Python code, with a focus on documenting nested functions.
If you haven't installed Doxygen on your system, you can do so by following the instructions on the official Doxygen website: Doxygen Installation.
Before using Doxygen, make sure your Python code has docstrings. Docstrings are string literals that occur as the first statement in a module, function, class, or method definition. They are used by Doxygen to generate documentation.
Create a Doxygen configuration file (e.g., Doxyfile) using the doxygen -g command. Open the configuration file and set the following options:
Feel free to customize other options based on your project's needs.
Run the following command in the terminal to generate the documentation:
This command processes your Python code and generates documentation in the specified output directory (./docs in this example).
Navigate to the page of the Python module or script containing the nested function. You should see the documentation for both the outer and nested functions.
Ensure that the docstrings for both functions include necessary details such as parameters, return types, and descriptions.
Congratulations! You've successfully generated documentation for your Python code using Doxygen, including nested functions. Documentation is crucial for code maintainability, and Doxygen makes it easy to create well-organized and readable documentation for your projects.
