![]() ![]() Stay tuned for more informative articles. In this article, we have studied different methods to reverse a string in python.We can also write the programs used in this article with exception handling using python try except to make the programs more robust and handle errors in a systematic way. Reversed String is: srennigeBroFnohtyP Conclusion We will first create an empty string and then we will add the characters in reverse order by iterating the reverse iterator returned by reversed() function as follows. We can use the reverse iterator to create the reverse of the input string. You can create a slice object using the built-in slice() function. Reverse a list, string, tuple in Python (reverse, reversed) Create slice objects with slice(). ![]() The reversed() method returns a reverse iterator of any iterable object passed to it as input argument. You can also use reverse() and reversed() to reverse lists or strings, tuples, etc. Reversed String is: srennigeBroFnohtyP Using reversed() method Otherwise we will take the last character out from the input_string and will call reverseString() function for the remaining part and will concatenate its output after the last character of the input_string as follows. First we will check if the input_string is empty, If yes then we will return the input_string. Suppose we define a function reverseString(input_string) to reverse the string. To use recursion to reverse a string, we will use the following procedure. Reversed String is: srennigeBroFnohtyP Reverse string using recursion ReversedString = reversedString+character In this way, a new string will be created which will be a reverse of the original string. Afterwards, we will take out characters one by one from the end of the list and then we will perform string concatenation to add the characters to the new string. ![]() In this method, First, we will convert the string into a list of characters and will create a new empty string. We can also use a list to reverse a string in python. Reversed String is: srennigeBroFnohtyP Reverse string using a Python list ReversedString = reversedString + character This can be easily understood from the following example. This will result in the creation of a new string which has characters in reverse order compared to the original string. Afterwards, We will access the string character by character from the end till start and will add it to the newly created string. To reverse a string using a for loop, we will first calculate the length of the string. Reversed String is: srennigeBroFnohtyP Reverse string using for loop Output: Original String is: PythonForBeginners Print("Reversed String is:", reversedString) ![]()
