- generator expression: (i for i in range(100))

range as a class:

class RangeExamp:
    def __init__(self, end, step=1):
        self.currt = 0
        self.end = end
        self.step = step

    def __iter__(self):
        return self

    def __next__(self):
        if self.curr >= self.end:
            raise StopIteration()
        else:
            return_val = self.current
            self.curr += self.step
            return return_val

range as a function:

def range_func(end):
    curr = 0
    while curr < end:
        yield curr
        curr += 1
