Think of itemgetter like a magical hand 🖐️ that quickly grabs specific items (elements, fields, or values) from a list, tuple, or dictionary — without writing loops.

It lives in the operator module.

🌈 Importing

from operator import itemgetter

🟢 Example 1: Grabbing List Items

from operator import itemgetter

fruits = ["🍎 Apple", "🍌 Banana", "🍇 Grapes"]

get_first = itemgetter(0)   # Grab item at index 0
get_two = itemgetter(0, 2)  # Grab multiple indices

print(get_first(fruits))   # 🍎 Apple
print(get_two(fruits))     # ('🍎 Apple', '🍇 Grapes')

📌 Colorful Analogy:
Imagine you’re at a fruit basket 🧺, and you tell the vendor:
👉 "Give me the 1st and 3rd fruit only."
That’s exactly what itemgetter does!

🔵 Example 2: Sorting with itemgetter

itemgetter really shines when sorting lists of tuples or dictionaries.

from operator import itemgetter

students = [
    ("Abhi", 85), 
    ("Neha", 92), 
    ("Ravi", 78)
]

# Sort by marks (index 1)
sorted_students = sorted(students, key=itemgetter(1))

print(sorted_students)
# [('Ravi', 78), ('Abhi', 85), ('Neha', 92)]

📌 Colorful Analogy:
Think of students standing in line 🧑‍🤝‍🧑.
You say: "Arrange them based on marks only 🎯, not names."
That’s itemgetter(1) in action!

🟡 Example 3: Dictionary Usage

from operator import itemgetter

person = {"name": "Abhi", "age": 32, "city": "Delhi"}

get_name_city = itemgetter("name", "city")
print(get_name_city(person))   # ('Abhi', 'Delhi')

📌 Colorful Analogy:
Like picking fields from a form 📋 –
👉 "I only need name and city, skip the rest."

🎯 Why Use itemgetter?

✅ Cleaner & faster than writing custom lambdas
✅ Works great for sorting & filtering
✅ Makes code readable & Pythonic ✨

🌟 Comparison: lambda vs itemgetter

💡 In short:
👉 itemgetter = a smart shortcut to grab or sort items without messy code. 🚀
