Python 3.x

You are to write an iterator that will output tuples of two elements from the given lists.

Given the class Pair you will need to implement the following methods:

__iter__ this will return an iterator

__next__ returns the next element

__init__ initialises the iterator class or

You may create a separate iterator class after __iter__ is called.

When next() is called with the iterator should return the next pair of elements. If the number of elements are uneven, the position the smaller list's elements are place would be replaced with None.

Once the iterator has finished returning elements, your iterator should raise StopIteration

SCAFFOLD:

Example 1 k -[0, 9, 8, 7, 6] pair - iter(Pair(1, k)) #Checking if print (next(pair)) #(1, e) print(next(pair)) #(2, 9) Example 2 k [0, 9, 8] pair -iter(Pair(1, k)) print (next(pair)) #(1, 0) print (next(pair)) #(2, 9) print(next(pair)) #(3, 8) print(next(pair)) #(4, None)
