Why does print(marks.sort()) show None?
Short answer. sort() changes the list itself and returns None.
Does sorted() change the original list?
No. It gives a new sorted list.
Remember
| sorted(): new list |
| sort(): same list, returns None |
You printed a sorted list, and got None. Why? Sorted gives back a new sorted list. Sort changes the list itself and returns None. So print the list after sort. Sorted gives a new list. Sort changes the same list and returns None.
