🎯 Tuples & Sets

# Tuple banana — () use karo
colors = ("Red", "Green", "Blue")
point  = (10, 20)

print(colors[0])   # Red
print(len(colors))  # 3

# Unpacking
x, y = point
print(x, y)  # 10 20

# Yeh error dega — tuple immutable hai!
# colors[0] = "Yellow"  # TypeError!

# Set banana — {} use karo
nums = {1, 2, 3, 2, 1}  # duplicates hata dega
print(nums)  # {1, 2, 3}

nums.add(4)
nums.remove(2)
print(nums)  # {1, 3, 4}

# Set operations
a = {1,2,3}
b = {2,3,4}
print(a | b)  # Union: {1,2,3,4}
print(a & b)  # Intersection: {2,3}
print(a - b)  # Difference: {1}

# Comparison
my_list  = [1, 2, 3]  # Mutable, ordered, duplicates ✅
my_tuple = (1, 2, 3)  # Immutable, ordered, duplicates ✅
my_set   = {1, 2, 3}  # Mutable, unordered, NO duplicates

print(type(my_list))   # list
print(type(my_tuple))  # tuple
print(type(my_set))    # set
