To reverse a string take a look at the following code : string = "hello world" print(string[::-1]) we can reverse a string by using list slicing. string[start:stop:step] Here string[::-1] As the first and second numbers(i.e start and stop numbers) in the above slice are not mentioned it's taken to be from start to end and as the step is -1 it prints the string from end to start By this we can get a reversed string. so finally the output would look like: dlrow olleh Hope you understood it😀

To further explain how it works: When splicing a list or in this case a string the syntax is somestring[start:stop:step]. We can omit the first two parameters since we want to go over all the elements which leaves us with step. By taking a negative step size we will go backwards.
