▶ Do the exercisesExercise 1 — Nested Codémon Battle Check
Create a nested condition to check both the Codémon's shield and health.
codemon_shield = 0
codemon_health = 100
____ codemon_shield <= 0:
____ codemon_health > 50:
print("Still fighting!")
____:
print("Critical!")
Options: if if elif else elif else
Hint : Nested conditions means multiple if statements inside each other. Remember to keep the indentation correct.
Exercise 2 — Complex Boolean Evaluation
x = 5
y = 10
if (x == y) or (x > 0 and y < 20):
print("Condition A")
elif x > y:
print("Condition B")
else:
print("Condition C")
Options
• ```"Condition A"```
• ```"Condition B"```
• ```"Condition C"```
• Nothing
Hint : Evaluate the complex condition step by step.

• False or True
• not False
Definitions
• False
• False
• True
• True
Exercise 4 — Codémon Attack Damage System

print("Critical hit!")
____ attack_damage >= 50:
print("High damage")
____ attack_damage >= 25:
print("Medium damage")
____:
print("Low damage")
Options: if elif else else if if elif else else if
Hint : Order conditions from highest to lowest.
Exercise 5 — Boolean Logic Evaluation
a = True
b = False
c = True
if not (a and b) or c:
print("Case 1")

Hint : Use nested conditions for multiple checks.
Exercise 7 — Operator Precedence
What will this code print?
x,y,z = 11,10,15

print("First")
elif x < z and y > x:
print("Second")
else:
print("Third")
Options
• ```"Third"```
• ```"Second"```
• ```"First"```
• Nothing
Hint : Remember the order: and is evaluated before or.
Exercise 8 — Boss Battle Condition
Complete the boss battle condition (trainer wins if Codémon has full health AND either a special attack OR magic power).
codemon_health = 100
has_special_attack = True
has_magic = False

print("Normal")
else:
print("Weak")
Options
• ```"Good"```

____ is_unlocked:
____ has_space:

print("Inventory full!")
____:
print("Chest locked!")
Options: if else elif if else elif
Hint : Think about the order of condition checks.
Exercise 14 — Parentheses Evaluation
What will this code print?
x, y, z = 10, 20, 15
if (x < y and y < z) or (x == z and y > x):
print("A")
elif x > z or y > z:
print("B")
else:
print("C")
Options
• ```"B"```
• ```"A"```
