執行效果如下：

新的知識點！

1）python獲取今天日期的方法：

>>> import time
>>> time.strftime(‘%Y-%m-%d‘)
‘2017-09-28‘
>>> type(time.strftime(‘%Y-%m-%d‘))
<type ‘str‘>

2）python獲取昨天的日期的辦法：

>>> import datetime
>>> now_time = datetime.datetime.now()
>>> yes_time = now_time + datetime.timedelta(days=-1)
>>> yes_time_nyr = yes_time.strftime(‘%Y-%m-%d‘)
>>> print (yes_time_nyr)
2017-09-27
>>> type(yes_time_nyr)
<type ‘str‘>

3）在 if __name__ == "__main__" 這一步的時候，我添加了一句 oss = "‘%s‘"%oss ，這是因為如果不加這句話，那麽傳遞給阿裏雲的bucket名稱格式不正確，正常的格式應該是：

{‘BucketName‘:‘lechangecloud‘}

不加這句話，得到的格式是缺少單引號的：

{‘BucketName‘:lechangecloud}
