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')
