Write Python Docstrings Effectively - Real Python

"Writing clear, consistent docstrings in Python helps others understand your code's purpose, parameters, and outputs. In this video course, you'll learn about best practices, standard formats, and common pitfalls to avoid, ensuring your documentation is accessible to users and tools alike. By the end of this video course, you'll understand that:"

"Docstrings are strings used to document your Python code and can be accessed at runtime. Python comments and docstrings have important differences. One-line and multiline docstrings are classifications of docstrings. Common docstring formats include reStructuredText, Google-style, NumPy-style, and doctest-style. Antipatterns such as inconsistent formatting should be avoided when writing docstrings."

Docstrings are strings used to document Python code and can be accessed at runtime. Comments and docstrings differ in purpose and accessibility. Docstrings can be one-line or multiline and should describe purpose, parameters, return values, and examples when appropriate. Common docstring formats include reStructuredText, Google-style, NumPy-style, and doctest-style. Best practices emphasize clear, consistent formatting and avoidance of antipatterns such as inconsistent formatting. Documentation should be accessible to both users and tools. Downloadable resources provide examples, templates, and practical exercises for applying formats and avoiding common pitfalls.
