💡 Highlight Snippet:

# A dictionary to store a player's stats, including a list as a value
player_profile = {
    "name": "Alex",
    "level": 5,
    "inventory": ["sword", "shield", "potion"],
    "is_active": True
}

# Accessing data
print(f"Player: {player_profile['name']}")
print(f"First inventory item: {player_profile['inventory'][0]}")
