In this particular example, the slice statement [::-1] means start at the end of the string and end at position 0, move with the step -1, negative one, which means one step backwards. Then using a reverse FOR LOOP, the items inside the Character Array are traversed and on by . In the code mentioned below, the object for the StringBuilder class is used. We can easily reverse a string by using python operator called extended slice operator.. Basically slice operator in python accepts 3 parameters (start, stop & step), In below example for start & stop index we pass no value, which will by default start index from 0 and end with n-1, then in step parameter we pass -1, which means string be . In Python use a for loop and swap the first and last items, the second and the one before the last item, and so on until the given list is reversed. To reverse a string in python without using the reverse function. Program2.c #include <stdio.h> #include <string.h> // function definition of the revstr () void revstr (char *str1) { // declare variable int i, len, temp; list1= [12,14,56,24,25,52,54] list1.reverse () print (list1) Syntax strrev (string) Before working on reversing the string without using function, let's have a look on how to reverse a string using string function strrev (), so that we can easily find the difference and gets clarity on the concept Example First, Use the split method to split a string into individual array elements. The len () function returns the string of items in an object. With two strings as operands, this operator returns a new string that results from joining the original ones.
