You're going to need to be more specific. In what way are they not normal functions? You call them like normal functions, providing arguments like normal functions, and receiving a result just like normal functions. If you call a function like iter(), you also get back an iterator, just as you do when you call a generator. Is iter() not a normal function? We also call classes, and callable instances, as if they were normal functions. Is that also a problem? I guess the answer depends on what we mean by "function": - an instance of FunctionType - a thing we call to get back a result or possibly both, as context requires. > def totally_not_a_generator(n): > while True: > if n % 2 == 0: > n //= 2 > else: > n = n * 3 + 1 > stealthily = n > yield stealthily > if n == 1: > return n I must admit, I'm a little perplexed. In what way is this totally not a generator? (To be precise, a generator function.)
