我正在尝试从边界框打印内容,问题是,如果图像有两个或更多面孔,则作业将返回两个或更多边界框,那么我将如何打印出来?

我试图编写一个循环来读取 str 'BoundingBox' 并打印,但它只返回第一个边界框两次。谁能给我一些想法?谢谢你

i=0
for bBox in response:
    print('found face at...')
    bBox = response['FaceDetails'][i]['BoundingBox']
    print("BoundingBox: ({}%)".format(bBox['Width']))
    print("BoundingBox: ({}%)".format(bBox['Height']))
    print("BoundingBox: ({}%)".format(bBox['Left']))
    print("BoundingBox: ({}%)".format(bBox['Top']))
    i+=i

格式为:

这是它返回的内容:
