🔑 Boolean Hacks in Python: A Few New Codes!

This notebook has short Boolean challenges. Edit the code where it says TODO to make it work.

Challenge 1: Positive Number

Fix the condition so it prints num is positive if the number is greater than 0.

num = 3  # Try changing this number!

# TODO: change the condition
if num < 0:  # <-- wrong, fix this
    print(num, "is positive")
else:
    print(num, "is NOT positive")

3 is NOT positive

Challenge 2: Is Even?

Change the condition so it prints num is even when the number is divisible by 2.

num = 7

# TODO: check if num is even
if num % 2 == 0:  # <-- not correct
    print(num, "is even")
else:
    print(num, "is odd")

7 is odd

Challenge 3: Teenager Check

Print Teenager if age is between 13 and 19 (inclusive). Otherwise print Not Teenager. Fix the condition.

age = 20

# TODO: fix the condition
if age > 12 and age < 20:  # <-- wrong
    print("Teenager")
else:
    print("Not Teenager")

Not Teenager

Challenge 4: Lamp Logic

We have two switches: a and b. The lamp should turn ON if at least one is True.

Fix the condition.

a, b = True, False

# TODO: fix condition for at least one True
if a or b:  # <-- wrong
    print("Lamp is ON")
else:
    print("Lamp is OFF")

Lamp is ON
