Day 3: Python Decision Maker

1 Your First Decision 🤔

💡Learn: The if statement asks a question. If the answer is YES (True), it runs the indented code!

age = 15

if age >= 13:
    print("You can watch PG-13 movies!")
    
print("This line always runs!")

🎮Experiment: Change age to 10, then run again. What changes? The first print disappears! That's because 10 is NOT >= 13.

2 Comparison Operators ⚖️

📊Learn: These symbols compare values and answer True or False!

Greater Than 5 > 3 Is 5 bigger than 3? True!

Equal To 10 == 10 Two equals signs! True!

Not Equal 7 != 5 Are they different? True!

Greater or Equal 15 >= 15 Same or bigger? True!

# See True and False answers!
print(5 > 3)
print(10 < 2)
print(7 == 7)
print("hello" == "world")
print(20 >= 20)

3 Matching Game! 🎯

🧩Challenge: Match each comparison with its result!

Comparisons:

10 > 5

8 == 3

7 <= 7

4 != 4

Results:

True ✅

False ❌

True ✅

False ❌

🎉Perfect! You understand comparisons!

4 If-Else Choices 🔄

🎲Learn: else runs when the if question is NO (False)! Only ONE block runs.

temperature = 30

if temperature > 75:
    print("🥵 Wear shorts!")
    print("Drink lots of water!")
else:
    print("🧥 Bring a jacket!")
    print("Stay warm!")
    
print("Have a great day!")

🔥Experiment: Change temperature to 80 (hot day) then 50 (cold day). See how ONE path runs!

5 Password Checker 🔐

🎮Build: Create a program that checks if you know the secret password!

secret = "python123"
password = input("Enter the password: ")

if password == secret:
    print("✅ ACCESS GRANTED!")
    print("Welcome back!")
else:
    print("❌ ACCESS DENIED!")
    print("Wrong password!")

🤫Tips: Try typing "python123" to get in! Then try a wrong password. Change the secret to your own!

6 Elif - Many Choices! 🌟

🎯Learn: elif means "else if" - check multiple conditions! Python stops at the FIRST true one.

score = int(input("Enter your test score: "))

if score >= 90:
    print("Grade: A 🌟")
    print("Outstanding!")
elif score >= 80:
    print("Grade: B 👍")
    print("Great job!")
elif score >= 70:
    print("Grade: C 👌")
    print("Good work!")
elif score >= 60:
    print("Grade: D 😅")
    print("You passed!")
else:
    print("Grade: F 💪")
    print("Keep studying!")

📊Test these scores: 95, 85, 72, 65, 45. Notice how it stops at the first true condition!

7 Final Quest: Adventure Game! 🏰

🗡️Epic Project: Create an adventure game with choices and consequences!

print("=== 🏰 THE ENCHANTED FOREST ===")
print()
name = input("Enter your hero name: ")
print()
print("Welcome,", name + "!")
print("You find three mysterious paths...")
print()
print("🌲 Path 1: Dark forest (scary sounds)")
print("🌊 Path 2: River crossing (sparkles)")
print("⛰️ Path 3: Mountain trail (wind howling)")
print()
choice = input("Which path? (1, 2, or 3): ")

if choice == "1":
    print()
    print("A friendly wolf guides you!")
    print("You find a magic sword! 🗡️")
    print("🎉 VICTORY!")
elif choice == "2":
    print()
    print("Mermaids sing to you!")
    print("They give you treasure! 💎")
    print("🎉 VICTORY!")
elif choice == "3":
    print()
    print("An eagle shows you the way!")
    print("You reach a golden castle! 🏰")
    print("🎉 VICTORY!")
else:
    print()
    print("You got confused and went home!")
    print("Try again tomorrow! 🏠")

💪Level Up Challenges:

Add a dangerous path with a BAD ending
Add a second choice after each path
Use age to unlock secret paths (if age >= 10)
Create your own story theme!
