Sometimes Python confuses me:
>>> range(2**128-1, 0, -1)
range(340282366920938463463374607431768211455, 0, -1)
>>> next(_)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'range' object is not an iterator
BUT, this is because of a difference between an iterable object and an iterator object.
for takes an iterable, and creates an "iterator" from that iterable, that is, calling iter on it.
given:
for i in j:
<body>
It can be rewritten as:
_iterobj = iter(j)
while True:
try:
i = next(_iterobj)
except StopIteration:
break
else:
<body>

@encthenet Interesting! Java draws the same distinction, but the Iterator has a separate hasNext() method rather than throwing an exception when the Iterator is empty.
