Python reversed()

The reversed() function returns an iterator object that provides access to the elements of an iterable (list, tuple, string, etc.) in reverse order.

 string = 'Python' result = reversed(string) # convert the iterator to list and print it print(list(result)) # Output: ['n', 'o', 'h', 't', 'y', 'P'] 

reversed() Syntax

The syntax of reversed() is:

 reversed(iterable)

The reversed() function takes a single argument.

• iterable - an iterable such as list, tuple, string, dictionary, etc.

reversed() Return Value

The reversed() method returns an iterator object.

Note: Iterator objects can be easily converted into sequences such as lists and tuples. They can also be directly iterated over using a loop.

Example 1: Access Items in Reversed Order

 text = 'cad' # access items of the string in reversed order for char in reversed(text): print(char)

Output

 d a c

Example 2: Reverse Dictionary Keys

 country_capitals = { 'England': 'London', 'Canada': 'Ottawa', 'Germany': 'Berlin' } # access keys in reversed order # and convert it to a tuple country = tuple(reversed(country_capitals)) print(country)

Output

 ('Germany', 'Canada', 'England')
