Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  First create the list, then specify the start index, then specify the stop index, then optionally specify the step.

  Why this is correct

  This is the correct order because you must have a list first, then define the slice boundaries in the correct sequence: start, stop, step.

• ✗

  First specify the start index, then create the list, then specify the stop index, then optionally specify the step.

  Why it's wrong here

  This is incorrect because you cannot specify an index before the list exists.

• ✗

  First create the list, then specify the stop index, then specify the start index, then optionally specify the step.

  Why it's wrong here

  This is incorrect because the slicing syntax requires start before stop; swapping them changes the slice.

• ✗

  First create the list, then specify the start index, then specify the step, then specify the stop index.

  Why it's wrong here

  This is incorrect because the step must come after the stop in the slicing notation [start:stop:step].
