    return boto.connect_s3('<aws-access-key', '<aws-secret-key>')

def list_keys():
    s3_conn = get_s3_conn()
    b = s3_conn ...

In Python, when you need to create a temporary file with a filename associated to it on disk, NamedTemporaryFile function in the tempfile module is the goto function. Here are some use cases that I think one might use it for.

Case #1: You simply need a named empty temporary ...

Today, I was curious to see this behavior of Mock() objects when using mock:

>>> from mock import Mock
>>> m = Mock()
>>> m.i_dont_exist
<Mock name='mock.i_dont_exist' id='139841609578768'>
