Sort without mutating the original list. Learn the syntax using an editable python example.
When to use it
Use this technique in collections, record processing and reusable transformations. Check the input types, any required imports, and whether the operation changes existing values or produces a new result.
Syntax
print(points)
Parameters
Inspect the literals, variables and function arguments used in the example. Replace values with compatible python types before testing.
Returns / effect
Expected demonstration result: [1, 2, 3]; [3, 1, 2].
Expected output
[1, 2, 3]; [3, 1, 2]
Common mistake and fix
Avoid assuming collection order or mutation semantics without checking the language API.
Good practices
Keep the example small, check its documented output, then adapt it to your own project with validation and error handling.
Practice exercise
Try changing one input in the sort without mutating the original list example. Predict how the output changes, then compare with the reference output.
Compatibility: Confirm support in your installed language/runtime version; some examples need modern standard libraries.

Show a hint
Change a single literal or input first; compare the result before making more edits.
