Question

Create a class called ASCIIDecoder this class should: A. Be an iterable object _iter_) B. Be an iterator _next_) Since it is an iterator of itself, the_iter__call should just initialize any variables used for iteration and return self. Functionally the ASCII decoder is initialized with a string and when iterated returns the ordinal (numeric) value for one character at a time...chr) and ord) are functions that can convert to and from ASCIl values. # Test Code: ad ASCIIDecoder ("C-3PO:hi") for n in ad: print (n,end-": ") print ("\n ") # should be able to reset when iterating a second time for n in ad: print (n, end-",") # # # OUTPUT: 67:45:51:80:79:58:104:105: 67,45,51,80,79,58,|04,105,

class ASCIIDecoder:

        def __init__(self, text):

                self._text = text

                self._current = 0;

        def __iter__(self):

                self._current = 0;

                return self

        def __next__(self):

                if self._current >= len(self._text):

                        raise StopIteration

                else:

                        self._current += 1

                return ord(self._text[self._current - 1])

ad = ASCIIDecoder('C-3PO:hi')

for n in ad:

      print(n, end=':')

print('\n---')

for n in ad:

        print(n, end=',')

Output:--
