This comprehensive guide explores Python'sreversedfunction, which returns a reverse iterator for sequences. We'll cover built-in sequences, custom objects, and practical examples of reverse iteration. Basic Definitions Thereversedfunction returns a reverse iterator object that accesses elements in reverse...
reversed() function The reversed() function is used to get a reverse iterator. Version: (Python 3.2.5) Syntax: reversed(seq) Parameter: Return value: An iterator in reverse order. Example: Python reversed() function # for string seqStr = 'Exercise' print(list(reversed(seqStr))) # for t...
The reversed() function returns an iterator object that provides access to the elements of an iterable (list, tuple, string, etc.) in reverse order. Example string = 'Python' result = reversed(string) # convert the iterator to list and print it print(list(result)) # Output: ['n', '...
