如下，为什么两个的结果不一样呢？求大佬指点一下方向。

C:\source\pythonProject>type yield_list.py
def combinations(hay, n, path):
    if len(path) == n:
        yield path
        return

    for x in hay:
        if path and (x in path or x < min(path)):
            continue

        path.append(x)
        yield from combinations(hay, n, path)
        path.pop()


print(list(combinations(['A', 'B', 'C'], 2, [])))
print('>>>>>>>>>>>>>>>>')
for x in combinations(['A', 'B', 'C'], 2, []):
    print(x, end=', ')

C:\source\pythonProject>python --version
Python 3.10.7

C:\source\pythonProject>python yield_list.py
[[], [], []]
>>>>>>>>>>>>>>>>
['A', 'B'], ['A', 'C'], ['B', 'C'],
