Reverse a Linked List - Python Function

To reverse a linked list in Python, you can define a function like the following:

def reverse_linked_list(head):
    prev = None
    current = head
    while current is not None:
        next_node = current.next
        current.next = prev
        prev = current
        current = next_node
    return prev
  

Make sure to call this function with the head of the linked list to reverse it.

```
