In Python, a docstring is a string literal that occurs as the first statement in a module, function, class, or method definition. Docstrings are used to provide documentation for your code and help users understand its purpose, usage, and functionality. They can be accessed using the . __doc__ attribute of the object.
Here's how docstrings work with examples:
A docstring at the beginning of a module provides an overview of the module's purpose, functionality, and usage.
A docstring inside a function describes what the function does, its parameters, and return values.
A docstring for a class should describe its purpose, attributes, methods, and usage.
Similar to function docstrings, method docstrings explain the purpose and usage of methods within a class.
You can access the docstrings using the .__doc__ attribute:
It's important to write clear and informative docstrings to make your code more readable and accessible to other developers. You can also generate documentation using tools like Sphinx based on docstrings.
Python docstrings are string literals placed as the first statement in modules, functions, classes, and methods to provide documentation for code. They help users understand the purpose, functionality, parameters, and usage of different elements in the codebase. Docstrings can be accessed using the . __doc__ attribute and are a crucial tool for creating clear and informative documentation for Python programs.
