Anatomy of Tuple Creation & Access
Tuples are defined with parentheses `()` and items separated by commas. They are ordered, and you access items using square brackets `[]`. Click the parts below.
point = (10, 25, "Origin")
x_coord = point[0] # Access first elementIdentify all parts!
Build-a-Tuple
Drag the pieces into the dark grey area to construct a tuple: `("AI", 2024)`. Remember the parentheses and comma!
Testing Immutability
Tuples are immutable - you can't change their elements after creation. Let's simulate this!
Assume we have `my_tuple = (10, 20, 30)`.
Try writing code to access the element at index 1 (value 20). Then, try writing code to change the element at index 0 to 99.
Spot the Tuple
Which of the following lines correctly define a tuple? Click the line(s) you think are tuples, then check your selection. Pay attention to parentheses `()` and commas `,`!
Tuple Mini Missions!
Apply what you've learned about tuples. Complete these small coding tasks.
Mission 1: Create a Simple Tuple
Create a tuple named `info` containing your favorite color (string) and your favorite number (integer). Then, print the `info` tuple.
Mission 2: Access an Element
Create a tuple `settings = ("High", True, 1080)`. Then, write a command to access and print only the second element (the boolean value).
Mission 3: Immutability Comment
Create a tuple `constants = (3.14, 9.8)`. On the next line, add a comment explaining why you *cannot* change the first element to `3.14159`.
