We can reverse the integer number in Python using the different methods. There are some other methods to reverse the list order by using slicing operator or reversed() method. The base condition of function is that if the length of the string is equal to 0, the string is returned.. # Python List Reverse Function rList = [10, 190, 120, 180, 120, 105] rList.reverse () print ("The Items of a Python List in Reverse Order are : \n", rList) Using Recursion Thus, it can be said that Python reversed() function can be used for reverse screening of data values of any data structure. While you could flip the resulting list around. This is a flexible and clean solution that relies on some advanced Python features—but it remains readable due to the clear naming of the reversed() function. How to declare an array in Python?

Joe Tatusko In Python to reverse a list, we have generally four ways. Using a While or For Loop to List Reverse. We can use the [::-1] slicing method to reverse a string through slicing, the reversed() and join() functions to reverse a string through reverse iteration, or recursion to reverse a string using a recursive function. But reverse() function is one of the easiest and simple one. But there are various ways to reverse the string. Example of reverse string in python using recursion..
