Creating an iterator from a dictionary.
class DictIterator:
def __init__(self, data):
self.data = list(data.items())
self.index = 0
def __iter__(self):
return self
def __next__(self):
if self.index >= len(self.data):
raise StopIteration
key, value = self.data[self.index]
self.index += 1
return f"{key}: {value}"
it = iter(DictIterator({"a": 1, "b": 2}))
print(list(it))
