Tuples
TUPLE in Python 👉 A Tuple is: Ordered Immutable (cannot be changed after creation) Allows duplicates Written inside parentheses () ✅ Example: # Creating a tuple t = (10, 20, 30) print(t) # (10, 20, 30) # Tuple with mixed data types t2 = (1, "apple", 3.5, True) print(t2) # (1, 'apple', 3.5, True) # Single element tuple (needs comma!) t3 = (5,) print(type(t3)) # <class 'tuple'> 📌 Important Tuple Functions / Methods ⚡ Since tuples are immutable , they have fewer methods. 1. count(x) – Counts occurrences t = (1, 2, 2, 3, 2) print(t.count(2)) # 3 2. index(x) – Returns index of element t = (10, 20, 30, 40) print(t.index(30)) # 2 3. len() – Returns length t = (1, 2, 3, 4) print(len(t)) # 4 4. Tuple Packing and Unpacking # Packing t = (10, 20, 30) # Unpacking a, b, c = t print(a, b, c) # 10 20 30 5. Tuple Concatenation & Repetition t1 = (1, 2) t2 = (3, 4) # Concatenation print(t1 + t...
