Output of Python Program | Set 10 (Tuples)

Tuples are immutable sequences in Python, meaning once created, you cannot modify them. They are efficient and useful for storing fixed collections of items. In this blog, we'll explore tuple operations and outputs through examples, followed by practice problems to help you master tuple handling.

Tuple Basics

Tuples are created using parentheses and support indexing, slicing, and concatenation:

tpl = (10, 20, 30, 40)
print(tpl[1])        # 20
print(tpl[-1])       # 40
print(tpl[1:3])      # (20, 30)
print(tpl + (50, 60))# (10,20,30,40,50,60)

This demonstrates accessing elements, slicing, and merging tuples.

Tuple Unpacking

Unpacking allows you to assign tuple elements to variables effortlessly:

a, b, c = (1, 2, 3)
print(a, b, c)       # 1 2 3

# Extended unpacking:
first, *middle, last = (5, 6, 7, 8, 9)
print(first, middle, last) # 5 [6,7,8] 9

Practice Problems

1. Swap two variables using tuple unpacking.
   

   a = 5
   b = 10
   # your code here
   print(a, b)  # Output should be: 10 5

   Solution

   a, b = b, a
   print(a, b)  # 10 5

2. Count occurrences of an element in a tuple.
   

   tpl = ('a', 'b', 'a', 'c', 'a', 'b')
   # your code here
   # Expected output: 3

   Solution

   count_a = tpl.count('a')
   print(count_a)  # 3

3. Unpack and skip middle elements.
   

   tpl = (100, 200, 300, 400, 500)
   # your code here
   # Expected: print(first, last) outputs: 100 500

   Solution

   first, *_, last = tpl
   print(first, last)  # 100 500
