That means that the conversion should take place without using any auxiliary list, by overwriting the existing elements of the specified list. EDIT: Some suggested I use xrange() instead of range() since range returns a list while xrange returns an iterator. If you need to access individual elements of a list in the reverse order, it's better to use reversed() function. last element first and so on.. 2) Using ListIterator (ii) By using the slicing technique. Given pointer to the head node of a linked list, the task is to reverse the linked list. In Python to reverse a list, we have generally four ways. Change Position of List Items With For Loop and Reversed() in Python. (iii) By using the iterative approach or loops. Add two numbers.

Providing the size of the list as an index to the ListIterator will give us an iterator pointing to the end of the list: ListIterator listIterator = list.listIterator(list.size()); This iterator now allows us to traverse the list in the reverse … Hello everyone, in this tutorial we’ll see different ways to reverse string in Python.
