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 + t2)   # (1, 2, 3, 4)

# Repetition

print(t1 * 3)    # (1, 2, 1, 2, 1, 2)

🔹 Difference Between List and Tuple

Feature	List ([])	Tuple (())
Mutability	Mutable (can change)	Immutable (cannot change)
Syntax	[]	()
Methods	Many (append, insert, remove, etc.)	Few (count, index)
Performance	Slower (because mutable)	Faster (because immutable)
Use Case	When data needs modification	When data should stay fixed
