Polishing with Visuals or Output Formatting

What You Will Learn in This Lesson

By the end of this lesson, you will know:

• Output formatting: Making text output clear and readable.
• Visual elements: Using formatting to improve presentation.
• Tables and lists: Organizing data visually.
• Color and styling: Enhancing terminal output.
• Professional presentation: Making projects look polished.

Why Formatting Matters

Well-formatted output makes your project:

Text Formatting

Use Python's string formatting to improve output:

# F-strings for formatting
name = "Alice"
age = 25
print(f"Name: {name:15} Age: {age:3}")

# Alignment
print(f"{'Task':<20} {'Status':>10}")
print(f"{'Buy groceries':<20} {'Done':>10}")

# Separators
print("=" * 50)
print("TASK MANAGER")
print("=" * 50)

# Lists with formatting
tasks = ["Task 1", "Task 2", "Task 3"]
for i, task in enumerate(tasks, 1):
    print(f"{i}. {task}")

Creating Tables

Format data in tables for clarity:

def print_task_table(tasks):
    """Print tasks in a formatted table."""
    print(f"{'#':<5} {'Task':<30} {'Status':<10}")
    print("-" * 45)
    for i, task in enumerate(tasks, 1):
        status = "Done" if task["completed"] else "Pending"
        print(f"{i:<5} {task['name']:<30} {status:<10}")

# Output:
# #     Task                           Status    
# ---------------------------------------------
# 1     Buy groceries                 Pending  
# 2     Finish homework                Done
