Let's break down the code step by step:
x=[1,2,3]: This line initializes a list named x with elements [1, 2, 3]. So, x is initially [1, 2, 3].
y=x[:]: This line creates a copy of the list x using slicing and assigns it to the variable y. The [:] slice notation creates a shallow copy of the entire list x. A shallow copy means a new list is created, but the elements themselves are references to the same objects as in the original list. So, y now also contains [1, 2, 3].
x.append(4): This line appends the integer 4 to the list x. After this line, x becomes [1, 2, 3, 4].
print(y): This line prints the contents of the list y. Since y was created as a copy of x, any changes made to x after the copy was created won't affect y.
Therefore, y still contains the original elements [1, 2, 3].
So, when you run the code, it will print [1, 2, 3], demonstrating that changes made to x after creating y do not affect y.
