A method named 'reverse_string' is defined, that takes a string as a parameter. idx := idx + 1. otherwise put string [i] into final string. In this section we will see how we can reverse a string using a for loop. Other approaches are less efficient, therefore, think twice before using them if the execution speed is crucial in your code. Using for loop and string concatenation. Using FOR Loop The idea behind this method is to use a reverse loop starting from the last index of the string to the 0th index. The interval parameter is used to select characters at specified intervals. Python Program to Reverse a String using Slicing. To reverse a Python's string you can slice it and end with index 0. See the example below: Notice that the output is in reversed order, this is because the object returned by the reversed method contains the string in reversed order. Program to Find Reverse of a String on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph, pattern, string etc. In this tutorial you'll learn the three major ways to reverse strings in Python: Option 1: Reversing a Python String With the " [::-1] " Slicing Trick Strings follow the sequence protocol in Python. A string is a list of characters, so it can be reversed using the reverse() function of the list. Why does the distance from light to subject affect exposure (inverse square law) while from subject to lens does not?
