Answer 1

删除一个对象：

response = bucket.delete_objects(
    Delete={
        'Objects': [
            {
                'Key': 'myObjectKey'
            }
        ]
    }
)

删除两个对象：

^{pr2}$

回答：

# Delete key(s)
forDeletion = [{'Key':'IMG_20160807_150118.jpg'}, {'Key':'IMG_20160807_150124.jpg'}]
response = bucket.delete_objects(Delete={'Objects': forDeletion})

for elem in response.get('Deleted'):
    print(elem['Key']) 

输出：

^{pr2}$
