Part 2: Communication in Software Engineering (Documentation)

1. Code Documentation

Key Elements of Good Code Documentation

• Function/Method Descriptions: Explain purpose and parameters.
• Code Comments: Clarify complex logic.
• Examples: Demonstrate usage.

Example of Documented Code in Python

def calculate_area(radius):
    """
    Calculates the area of a circle.

    Parameters:
    - radius (float): Circle's radius.

    Returns:
    - float: Calculated area.

    Example:
    >>> calculate_area(5)
    78.54
    """
    import math
    if radius < 0:
        raise ValueError("Radius cannot be negative")
    return math.pi * radius ** 2

Pro-tip: Use interactive environments like repl.it or collab to give invaluable hands-on. Try the code above in Google Collab!
