@Python_Dv C x is a generator object. It's an iterator that yields values one by one on demand. In the first loop, all the values are exhausted. Once the generator object is exhausted, it cannot be reset or reused, therefore, there is no output for second iteration.
@Python_Dv Interesting question! To determine the output, Python concepts like variable scope and type conversion must be considered.
@Python_Dv The answer hinges on understanding how list slicing works in Python.
@Python_Dv 答案：Cx = (i for i in range(3)) 这行代码创建了一个生成器表达式，生成器是一种迭代器。当第一个 for 循环 for i in x: 执行时，它会从生成器 x 中依次取出元素并打印，执行第二个 for 循环 for j in x: 时，由于生成器已无元素可迭代，不会再输出任何内容。因此最终的输出结果是 0 1 2 。
