Most programmers, if else, if else, if else, instead of just switching to the matching case 😁 Instead of let day = 3; if (day === 1) { console.log("Monday"); } else if (day === 2) { console.log("Tuesday"); } else if (day === 3) { console.log("Wednesday"); } else { console.log("Other day"); } Use this let day = 3; switch(day) { case 1: console.log("Monday"); break; case 2: console.log("Tuesday"); break; case 3: console.log("Wednesday"); break; default: console.log("Other day"); } In Python use this value = 3 match value: case 1: print("One") case 2: print("Two") case 3: print("Three") case _: print("Other") Python 3.10+
⚠️ Common Syntax Errors (Mistakes in Writing Code) Mistake Error You’ll See Missing quotes SyntaxError: invalid syntax Typing Print instead of print NameError: name 'Print' is not defined Forgetting brackets SyntaxError: unexpected EOF
🛑 Rules of Python (VERY IMPORTANT) ✅ Do: Use lowercase for commands: print, not Print Use quotes for text: "Hello" or 'Hello' Use round brackets () for function calls ❌ Don't: Forget quotes around text: print(Hello) ❌ Use capital letters randomly: Print("Hi") ❌ Miss a bracket: print("Hi" ❌
