The syntax of the reverse() method is: list.reverse() reverse() parameter . The for loop will use all 26 numbers from 65 to 90, each will be used to print a corresponding upper case alphabet. In loops, range() is used to control how many times the loop will be repeated. ; Using for loop and appending characters in reverse order; Using while loop to iterate string characters in reverse order and append them; Using string join() function with reversed() iterator; Creating a list from the string and then calling its reverse() function; Using Recursion; 1.1) Python Reverse String using Slicing The range() function enables us to make a series of numbers within the given range. Return Value. Here are some alternate and easy ways to reverse a string. index variable is initialized with value length of the list - 1. In this tutorial, learn how to loop over Python list variable. Once you get the logic, you can write the program in any language, not only Python. This program allows the user to enter a string.

For example, let us suppose the user entered 123 than we have to reverse the number to 321. First, we have calculated the length of the list using the len() method. For Loops using range() One of Python’s built-in immutable sequence types is range(). Since lists in Python are dynamic, we don’t actually have to define them by hand. It will make easy to understand the program logic. Using string join() function with reversed() iterator. View all tutorials Reference Materials. It neither reverses a list in-place, nor does it create a full copy. Using while loop to iterate string characters in reverse order and append them. Let’s see all the different ways to iterate over a list in Python, and performance comparison between them. List Methods ...

Some of the common ways to reverse a string are: 1. Create a List with a Loop. Note: It is suggested not to use this type of loops as it is a never ending infinite loop where the condition is always true and you have to forcefully terminate the compiler. Python Tuples Access Tuples Update Tuples Unpack Tuples Loop Tuples Join Tuples Tuple Methods Tuple Exercises. Python list method reverse() reverses objects of list in place.. Syntax. I know about this. Explanation : The commented numbers in the above program denote the step number below : We are using the same list as the above example. First, we understand the algorithm of this program. link brightness_4 code # Python3 code to iterate over a list. It was not necessary to loop the range() and using list() method we could directly convert the output from range to list format.
