    print(object)

• 実行する

$ python s3_ls.py
s3.ObjectSummary(bucket_name='az-test-datalake', key=u'system01/')
s3.ObjectSummary(bucket_name='az-test-datalake', key=u'system01/table01/')
s3.ObjectSummary(bucket_name='az-test-datalake', key=u'system01/table01/table01_20180101.txt')
s3.ObjectSummary(bucket_name='az-test-datalake', key=u'system01/table01/table01_20180102.txt')

ところで boto の名前の由来は

https://github.com/boto/boto3/issues/1023

boto = Amazon river dolphin
issue の会話を読んでいくと、アマゾン川に生息する アマゾンカワイルカ にちなんで boto と名付けられたみたい。

Boto is a Portuguese name given to several types of dolphins and river dolphins native to the Amazon and the Orinoco River tributaries. A few botos exist exclusively in fresh water, and these are often considered primitive dolphins.
