如何在python中使数字可迭代？

def generate_numbers(start, end):
    while start <= end:
        yield start
        start += 1

numbers = generate_numbers(1, 10)
for number in numbers:
    print(number)

class NumberIterator:
    def __init__(self, start, end):
        self.current = start
        self.end = end
    
    def __iter__(self):
        return self
    
    def __next__(self):
        if self.current > self.end:
            raise StopIteration
        else:
            number = self.current
            self.current += 1
            return number

numbers = NumberIterator(1, 10)
for number in numbers:
    print(number)
