Practice 1: Greet & Add

Name: Ava • a: 2 • b: 3

Why?

Practice a single function that prints a greeting and a simple sum.

What you’ll type

  • Make greet_and_add(name, a, b) that:
  • ① prints Hello, NAME! (uppercase)
  • ② prints a + b
⭐ Stars: 0
🐞 Bugs: 0

      Hint
      
    
        
  • print("Hello, " + name.upper() + "!")
    • 
        
  • print(a + b)
    •
