Exam PCEP-30-02 topic 1 question 59 discussion

Let's analyze the given code snippet step-by-step to determine which statement is true: nums = [] vals = nums[:] vals.append(1) nums = [] nums is initialized as an empty list: []. vals = nums[:] vals is created as a shallow copy of nums. Since nums is an empty list, vals will also be an empty list: []. vals.append(1) 1 is appended to the list vals. After this operation, vals will be: [1]. Final State of the Lists nums remains an empty list: []. vals is now: [1]. Comparing the Lengths The length of nums is 0. The length of vals is 1. Conclusion vals is longer than nums. Therefore, the correct statement is: C. vals is longer than nums

c is the correct answer. we have a swallow copy here so vals is greater since nums is not getting appended but only vals.
