从没有目录名的 S3 存储桶和目录中获取文件名？

Question

I have connected to S3 and got all files in my S3 bucket foo and from folder poo. All my files are in S3://foo/poo .

Running this code returns:

[i.key for i in s3_resource.Bucket(foo).objects.filter(Delimiter='/', Prefix='poo/')]

I am getting:

['poo/',
 'poo/a.png',
 'poo/b.png',
 'poo/c.png',
.....]

How can I get rid of poo/ ?

Answer 1

use rsplit with max splits equal to 1 and take the 2nd value

[i.key.rsplit('/', 1)[1] 
 for i in s3_resource.Bucket(foo).objects.filter(Delimiter='/', Prefix='poo/')
 if i.key.rsplit('/', 1)[1] != '']

should give

['a.png', 'b.png', 'c.png', ...]

Answer 2

[i.key for i in s3_resource.Bucket("foo").objects.filter(Delimiter='/', Prefix='poo/') if i.key != 'poo/']
