Lists and Their Magical Powers

Explore how superheroes manage teams and inventories using lists in Python.

Python's List Magic Show 🎩✨

Lists are like teams of superheroes—dynamic and powerful.

The Shape-Shifting Lists 🔄

Lists can change, just like a superhero adapting to challenges.

team = ["Iron Man", "Captain America", "Thor"]
team.append("Hulk")  # Add a new member
team.remove("Iron Man")  # Member leaves
print(team)
# Output: ['Captain America', 'Thor', 'Hulk']

Question: How can we add multiple members at once?

Example:

new_members = ["Black Widow", "Hawkeye"]
team.extend(new_members)
print(team)
# Output: ['Captain America', 'Thor', 'Hulk', 'Black Widow', 'Hawkeye']

Elemental Conjuring and Banishment 🌟🚫

Summon and dismiss elements in a list.

inventory = ["Shield", "Armor"]
inventory.insert(1, "Helmet")  # Add at specific position
lost_item = inventory.pop(0)   # Remove by position
print(f"Inventory: {inventory}, Lost: {lost_item}")
# Output: Inventory: ['Helmet', 'Armor'], Lost: Shield

Task

Replace "Armor" with "Nano Suit" in the inventory.

Answer

index = inventory.index("Armor")
inventory[index] = "Nano Suit"
print(inventory)
# Output: ['Helmet', 'Nano Suit']

The Alchemy of Lists: Merging and Cloning 🔮

Merging Teams

team_a = ["Spider-Man", "Doctor Strange"]
team_b = ["Black Panther", "Captain Marvel"]
united_team = team_a + team_b
print(united_team)
# Output: ['Spider-Man', 'Doctor Strange', 'Black Panther', 'Captain Marvel']

Question: How can we sort the united team alphabetically?

Answer

united_team.sort()
print(united_team)
# Output: ['Black Panther', 'Captain Marvel', 'Doctor Strange', 'Spider-Man']

Cloning Gadgets

gadgets = ["Web Shooter"] * 3
print(gadgets)
# Output: ['Web Shooter', 'Web Shooter', 'Web Shooter']

Arcane Copies and Mystical Sorts 📜

Shadow Copying

original = ["Thor's Hammer", "Captain's Shield"]
copy = original[:]
copy.append("Iron Man's Suit")
print(f"Original: {original}, Copy: {copy}")
# Output: Original: ["Thor's Hammer", "Captain's Shield"], Copy: ["Thor's Hammer", "Captain's Shield", "Iron Man's Suit"]

Question: What happens if we modify the original list after copying?

Example:

original.remove("Thor's Hammer")
print(f"Original: {original}, Copy: {copy}")
# Output: Original: ["Captain's Shield"], Copy: ["Thor's Hammer", "Captain's Shield", "Iron Man's Suit"]

The Alchemy of List Manipulation 📜✨

Dive into transforming lists, from doubling powers to orchestrating order.

Doubling Strength

# Amplifying power
player_stats = [10, 20, 30]
for i in range(len(player_stats)):
    player_stats[i] *= 2
print("Amplified Stats:", player_stats)
# Output: Amplified Stats: [20, 40, 60]

Advanced List Comprehension 🚀

Efficiently process lists.

Character Count in Names

heroes = ["Batman", "Superman", "Wonder Woman"]
name_lengths = [len(hero) for hero in heroes]
print(name_lengths)
# Output: [6, 8, 12]

Filtering Heroes

long_named_heroes = [hero for hero in heroes if len(hero) > 6]
print(long_named_heroes)
# Output: ['Superman', 'Wonder Woman']

Question: How can we create a list of heroes' names in uppercase?

Answer

uppercase_heroes = [hero.upper() for hero in heroes]
print(uppercase_heroes)
# Output: ['BATMAN', 'SUPERMAN', 'WONDER WOMAN']

Conclusion

By mastering lists, you've learned how to manage collections of items effectively. Whether it's assembling a team of heroes or managing an inventory of gadgets, lists are essential tools in your Python journey.
