Multiple choice questions on documenting function parameters and return values

📚 Quick Study Guide

• 📝 Purpose of Documentation: To explain what a function does, what parameters it expects, and what it returns. This makes code easier to understand and maintain.
• 🏷️ Parameter Documentation: Describes each parameter a function accepts, including its data type, meaning, and any default values.
• ↩️ Return Value Documentation: Specifies the data type and meaning of the value a function returns. If a function has side effects, those should also be documented.
• 💻 Docstrings: Common way to document Python code. They are multiline strings enclosed in triple quotes (`'''Docstring goes here'''` or `"""Docstring goes here"""`) placed immediately after the function definition.
• 🧰 Tools and Conventions: Tools like Sphinx can automatically generate documentation from docstrings. Consistent formatting (e.g., using reStructuredText or Markdown within docstrings) is crucial for these tools to work correctly.
• 💡 Benefits:
  • 🧑‍🤝‍🧑 Collaboration: Easier for teams to work together.
  • 🐛 Debugging: Simplifies debugging by providing clear expectations.
  • 🛠️ Maintainability: Makes code easier to update and modify in the future.
• ✍️ Example (Python): python def add(x, y): '''Adds two numbers together. :param x: The first number. :type x: int or float :param y: The second number. :type y: int or float :returns: The sum of x and y. :rtype: int or float ''' return x + y
