Count unique elements in collection Program Code

# Count unique elements in various collections
# List
list_data = [1, 2, 2, 3, 3, 3, 4, 5, 5]
unique_count = len(set(list_data))
print(f"List: {list_data}")
print(f"Unique elements: {unique_count}")

# Tuple
tuple_data = (1, 1, 2, 2, 3, 4, 4, 5)
print(f"\nTuple: {tuple_data}")
print(f"Unique elements: {len(set(tuple_data))}")

# String
string_data = "programming"
print(f"\nString: '{string_data}'")
print(f"Unique characters: {len(set(string_data))}")

# Mixed data
mixed = [1, 'a', 2, 'a', 1, 'b', 3]
print(f"\nMixed: {mixed}")
print(f"Unique elements: {len(set(mixed))}")
