The easiest way to reverse a list in Python isusing slicing([::-1]), which creates a new reversed list without modifying the original: numbers=[1,2,3,4,5]reversed_numbers=numbers[::-1]print(reversed_numbers)# O

range()is a Python built-in function that outputs a list of a range of numbers. range(start,stop,step) This function has 3 arguments; the main required argument is the second argumentstop, a number denoting where you want to stop. There are 2 optional arguments,startspecifies where you sh...
In this article, we are discussing the reverse list in Python. In Python, reverse() is an inbuilt function used for reversing the list where this method does not return any value, which returns the list with the reverse items in the given list. This function does not create and copy any...
Syntax: You can call this method on each list object in Python. Here’s the syntax: list.reverse() 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 ...

9.Is there an alternative way to reverse a list in Python list method? Yes, a list can be reversed using slicing with the [::-1] syntax or the reversed() function for creating an iterator. 10.What is the time complexity of the Python reverse() method?

The reversed() function in python accepts a sequence of elements and returns a reverse iterable object. Similarly, we can also reverse a tuple using the slicing syntax [::-1] in python. Here is an example: a = (1,2,3) print (a[::-1]) In the example above, we have ommited the...
