Solution 1

You are not supposed to assign it to any variable, when you append something in the list, it updates automatically. use only:-

last_list.append(p.last)

if you assign this to a variable “last_list” again, it will no more be a list (will become a none type variable since you haven’t declared the type for that) and append will become invalid in the next run.

Solution 2

list is mutable

Change

last_list=last_list.append(p.last_name)

to

last_list.append(p.last_name)

will work
