reverse()is a built-in function in Python. In this method, we will not create a copy of the list. Instead, we will modify the original list objectin-place. It means we will copy the reversed elements into the same list. Thereverse()method will not return anything as the list is reve...

Let us see a simple example for a reverse() function which is used for reversing the elements in the given list. This function can be used to reverse the contents of the list object at in-place, which means there is no need to create a new list; instead, it just modifies the origina...
Arguments:The reverse method doesn’t take any arguments. Return value:The methodlist.reverse()has return valueNone. It reverses the elements of the list in place (but doesn’t create a new list). Thus, a return value is not needed. ...
