# Scope

# enemies = 1

# def increase_enemies():
#     enemies = 2
#     print(f"enemies inside func {enemies}")

# increase_enemies()
# print(f"enemies outside func {enemies}")

# Output - enemies inside func 2 & enemies outside func 1

# Local Scope

# def drink_potion():
#     potion_strength = 2
#     print(potion_strength)

# drink_potion()
# print(potion_strength)

# the above code gives an error as potion_strength not defined

# Global Scope
# player_health = 10

# def drink_potion():
#     potion_strength = 2
#     print(potion_strength)
#     print(player_health)

# drink_potion()
# Output 2 & 10
# player_health = 10
# def game():
#     def drink_potion():
#         potion_strength = 2
#         print(potion_strength)
#         print(player_health)
#     drink_potion()
# game()
# print(player_health)
# Output 2, 10 & 10

# Block Scope

# game_level = 3
# def create_enemy():
#     enemies = ["Skeleton", "Zombie", "Alien"]
#     if game_level < 5:
#         new_enemy = enemies[0]
#     print(new_enemy)

# Modifying Global Scope
# correct way of giving a global scope

# enemies = 1

# def increase_enemies():
#     print(f"enemies inside function: {enemies}")
#     return enemies + 1

# enemies = increase_enemies()
# print(f"enemies outside function: {enemies}")
