📚 Prerequisites​

Before starting these exercises, make sure you've read:

🔰 Starter: Hello, You!​

Time: 10 minutes

Write a program that prints a personalised greeting.

Learning Objectives​

  • Use the print() function with a string
  • Store a name in a variable and use it in output
  • Write a single-line comment

Starter Code​

# Starter: Hello, You!
# TODO: Create a variable called 'name' with your name
# TODO: Print "Hello, <name>! Welcome to Python."

# Your code here 👇

Expected Output​

Hello, Alice! Welcome to Python.

⭐ Medium: ASCII Art Sign​

Time: 15 minutes

Use multiple print() statements and comments to create an ASCII art sign for a shop.

🏆 Hard: Interactive Digital Business Card​

Time: 25 minutes

Build a mini digital business card that uses variables, multiple print statements, and the REPL to display formatted information about a person or business.

Learning Objectives​

  • Combine variables, strings, and print() in a meaningful program
  • Format output using f-strings
  • Write clear, readable code with appropriate comments
  • Run code in the REPL vs running a script

Starter Code​

# Hard: Digital Business Card
# TODO: Create variables for:
#   - name, role, company, email, phone, location
# TODO: Print a neatly formatted business card using f-strings
# TODO: The card should have a border and aligned text

# Starter variables
name = "Alex Johnson"
role = "Python Developer"
company = "TechStartup Inc."
email = "[email protected]"
phone = "+1-555-0123"
location = "San Francisco, CA"

# Your code here 👇

Expected Output​

╔══════════════════════════════════════╗
║         ALEX JOHNSON                ║
║         Python Developer            ║
║                                      ║
║   Company:  TechStartup Inc.         ║
║   Email:    [email protected]      ║
║   Phone:    +1-555-0123              ║
║   Location: San Francisco, CA        ║
║                                      ║
║   "Code is like humor. When you      ║
║    have to explain it, it's bad."    ║
╚══════════════════════════════════════╝

💡 Tips for Success​

  • Open your terminal and type python3 to enter the REPL — test small snippets there.
  • Use print() with multiple arguments: print("Hello", "World") adds a space automatically.
  • Comments start with # — use them to plan your code before writing it.
  • If you see SyntaxError: invalid syntax, check for missing quotes or parentheses.
