reversed(seq)

Returns a reverse iterator over the specified sequence seq. The sequence must have a __reversed__() method or both a __len__ and a __getitem__ method with integers starting from 0.

Parameters¶

The reversed() function takes one parameter:

• sequence_object — an indexable object to reverse (can be a tuple, string, list, range, etc.)

Note: Since sets and dictionaries cannot be indexed, they are not considered sequence objects.

Return Value¶

The reversed() function returns:

• a reversed iterator of elements in the sequence object

Examples¶

seq_tuple = ('C', 'A', 'T', 'S')

# Reverse the tuple object
print(list(reversed(seq_tuple)))

seq_range = range(3, 7)

# Reverse the range
print(list(reversed(seq_range)))

seq_list = [1, 2, 4, 3, 5]

# Reverse the list
print(list(reversed(seq_list)))

# Output
['S', 'T', 'A', 'C']
[6, 5, 4, 3]
[5, 3, 4, 2, 1]
