Answer 1

If you want to do it with regular expressions, you can do the following:

>>> import re
>>> uri = 's3://my-bucket/my-folder/my-object.png'
>>> match = re.match(r's3:\/\/(.+?)\/(.+)', uri)
>>> match.group(1)
'my-bucket'
>>> match.group(2)
'my-folder/my-object.png'

This has the advantage that you can check for the s3 scheme rather than allowing anything there.
