Let’s dive into the world of structured programming in Python!

What is Structured Programming?

Imagine building a house without a blueprint – it would be chaotic! Structured programming is like having that blueprint for your code. It’s an approach that emphasizes breaking down complex problems into smaller, manageable modules using specific control structures:

• Sequence: Instructions are executed one after another in the order they appear.
• Selection (Decision Making): Code executes different blocks based on conditions (using if, elif, and else statements).
• Iteration (Looping): Repeating a block of code multiple times (for and while loops are your tools here).

Think of it like following a recipe: you add ingredients in order, make decisions based on taste (“add more salt if needed”), and repeat steps until the dish is ready.

Why Is Structure Important?

• Readability: Well-structured code is easy to understand, both for yourself and others who might work with it.
• Maintainability: Making changes or fixing bugs becomes simpler when your code is organized.
• Efficiency: Structured programs tend to be more efficient because they avoid redundant code and unnecessary jumps.

Python’s Embrace of Structure

The beauty of Python lies in its inherent support for structured programming. Let’s see it in action:

# Calculate the area of a rectangle

length = 10
width = 5

# Selection (Decision Making)
if length > 0 and width > 0:
  area = length * width
  print("The area of the rectangle is:", area)
else:
  print("Invalid dimensions. Length and width must be positive.")

Explanation:

1. Variables: We define length and width.
2. Selection (if-else): We check if both dimensions are positive. If they are, we calculate the area. Otherwise, we print an error message.
3. Output: The result is printed to the console.

Common Mistakes Beginners Make

• Deep Nesting: Avoid excessive nesting of if/else statements – it can make your code hard to read. Consider refactoring into smaller functions if needed.
• Lack of Comments: Explain what your code does using clear comments (starting with #).

Tips for Efficient and Readable Code

• Meaningful Variable Names: Use names that reflect the purpose of the variable (customer_name instead of cn).
• Function Decomposition: Break down larger tasks into smaller functions, each performing a specific action. This improves reusability and organization.
