Let’s open up the interpreter and see how this works. ; We can supply a custom object as reversed() function argument if it has __reversed__() method or supports the sequence protocol. Generic selectors. Return Value. If you only want to iterate over the list’s elements in reverse order prefer using the reversed() function, as it is faster than reversing the elements in place`. Using while loop to iterate string characters in reverse order and append them. This Python program finds reverse of a given integer number using recursion. We can use the [::-1] slicing method to reverse a string through slicing, the reversed() and join() functions to reverse a string through reverse iteration, or recursion to reverse a string using a recursive function. The reversed() function returns an iterator that accesses the given sequence in the reverse order. Some of the common ways to reverse a string are the following. list.reverse() Parameters. It doesn’t create a new list object instead straightway modifies the original copy. While you could flip the resulting list around, sorted() contains a reverse parameter that you can set to True, and the resulting list will be reversed for you. (ii) By using the slicing technique.
