What method is used to reverse a list in Python?

The method used to reverse a list in Python is list.reverse(). This method directly modifies the original list by reversing the order of its elements in place. By using this method, you do not create a new list; instead, the existing list is altered. This is beneficial in terms of memory efficiency, as it avoids the overhead of creating an additional copy of the list.

The list.reverse() method is straightforward to use—simply call it on a list variable without any arguments, and it will reverse the elements of that list. This is essential functionality in Python because list manipulation is a common task when programming.

The other options presented do not correspond to any standard method used to reverse a list in Python. The presence of these non-existent methods may cause confusion, as they imply operations that are unrelated to reversing a list.
