# Backward Iteration in Python Backward iteration is a mechanism of iterating through a sequence of elements starting from the last element and moving towards the first element. This can be done using the built-in functions in python such as reversed() and reversed_iterator(). The reversed() returns a reversed iterator, while the reversed_iterator() returns an iterator. Both of the functions work on any iterable object such as a string, a list, a tuple, etc. Backward iteration can be useful in various scenarios. For example, when iterating through a list or a sequence of elements in backwards order, it can help to find the last occurrence of a particular element or to identify the differences between elements quickly. Moreover, when dealing with recursive algorithms, backward iteration can help to simplify the logic and make the code more efficient. It can also be used in list comprehensions to reverse the order of elements in a list.

Backward Iteration is a type of looping technique in Python that allows you to iterate over a sequence of elements in a reverse order. This type of looping is useful when you want to loop over a sequence of elements but need to start at the end of the sequence and work your way back. Below is a sample code for backward iteration in Python: #Declare a list of elements elements = [1, 2, 3, 4, 5] #Loop over the sequence in reverse order for x in reversed(elements): print (x) #Output: #5 #4 #3 #2 #1
