Tuples

Concept

Tuples

Tuples are like lists but immutable, meaning they cannot be changed after creation, which is great for fixed groups of values.

Because they can't change, tuples can be used as dictionary keys, while lists cannot.

By the end of this lesson
  • Explain the core idea behind Tuples.
  • Predict output before running a change.
  • Test one realistic and one unusual input.
  • Use the result to make the next decision.
How to study this page

Self-check before continuing

Without looking at the example, describe what changes when you modify one input in Tuples. Then reopen the editor and prove your explanation with a small test.

You are ready to continue when you can predict, test, and explain the result.

Your turn

Create a tuple representing a date with day, month, and year, and unpack it into three variables.
