Python Tuples

A tuple is just like a list — it can store multiple items in a single variable, but with one key difference: tuples cannot be changed once created. That means you can’t add, remove, or update items after the tuple is defined.

What is a Tuple?

Tuples are ordered — the order in which you define the items is preserved.
Tuple elements are separated by commas ,.
Tuples are written inside round brackets () instead of square brackets [].
Tuples are immutable (unchangeable after creation).

Example 1 – Numbers and Colors in Tuples

				
					numbers = (10, 20, 20, 30, 50, 40, 60)
colors = ("Red", "Green", "Blue")

print(numbers)
print(colors)

Output:

				
					(10, 20, 20, 30, 50, 40, 60)
('Red', 'Green', 'Blue')

As you can see, tuples can hold duplicate items too, just like lists.

Example 2 – Mixed Data Types in a Tuple

Tuples can also store different types of values — strings, numbers, floats — all together.

				
					profile = ("Arshyan", 21, "Software Engineer", 9.2)
print(profile)

Output:

				
					('Arshyan', 21, 'Software Engineer', 9.2)

This flexibility makes tuples great for storing related but different pieces of information.

Key Takeaway:

If you need a container where the data shouldn’t be changed, use a tuple instead of a list. They’re safe, fast, and very memory-efficient.
