Need Help! I want the frut list to not get changed when changing the attribute of an object A.

Answer 1

That happens because you are dealing with references only. If you want the list in frut to be its own list, not a reference to A's list, then you can create a copy:

frut.append(A.fruits_list.copy())

Or by passing the list to the list constructor (kind of saying create a list from this list)

frut.append(list(A.fruits_list))

Edit: another suggested possibility is to use += instead of .append(). An explanation as to why that works would be appreciated :)

Answer 2

Thanks very much,
I was also thinking of a way to take the static attribute value of an object instead of its references when appending to frut list.

that's good your methods work!
