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

@PythonPr [1,4,3] as the list is passed a reference.

@PythonPr Answer: B: [1,4,3] x = [1,2,3]: A list object is created in memory, and the variable x is assigned as a reference to this list. y = x: This does not create a copy of the list. Instead, it makes the variable y point to the same list object in memory that x points to.

@PythonPr • x = [1, 2, 3] → x is a list. • y = x → y is a reference to the same list object as x. • y[1] = 4 → This modifies the second element of the list (index 1) to 4. • Since x and y point to the same list, the change is reflected in both. Correct Answer B: [1, 4, 3]

@PythonPr B. [1,4,3] since x and y are pointing to the same object. A change in the original list by either x or y will be reflected in the output of either.

@PythonPr B

@PythonPr Is B y [1] changes the second element of the list to 4... the output will be: [1, 4, 3]

@PythonPr A

@PythonPr D syntax error. The instruction print (x) must be indented.

@PythonPr B

@PythonPr c

@PythonPr A

@PythonPr Option B Because the expression y[1] =4 is updating the element at index 1 which is 2 to 4

@PythonPr B. [1, 4, 3]. Lists are mutable hence x an y point to the same object.

@PythonPr A

@PythonPr B

@PythonPr B. [ 1 , 4 , 3 ] ... .@PythonPr

@PythonPr B

@PythonPr B

@PythonPr B One Good Health. Good food.

@PythonPr B

@PythonPr [1,4,3]

@PythonPr B

@PythonPr B, because y points to the same list as x, so modifying y[1] also changes x, resulting in [1, 4, 3].
