Python Question / Quiz; What is the output of the following Python code, and why? Comment your answers below!

@PythonPr The correct option is B: [1, 4, 3] In Python, when a list is assigned to a new variable (e.g., y = x), the new variable is not a copy of the list; instead, both variables refer to the same list object in memory. This is known as assignment by reference.

@PythonPr Answer: B x and y reference the same list. Here x = [1, 2, 3]; y = x y[1] = 4 x becomes [1, 4, 3]. Use x[:] or list(x) if you want an actual copy.

@PythonPr The answer is B. In Python, variables don’t store lists, they store references. So modifying y also modifies x Output: [1,4,3]

@PythonPr B is the correct answer.
