In the same way that exceptions can have a tuple of
types specified and isinstance can take a tuple of
types, str.startswith and endswith could take a tuple
of possible prefixes/suffixes.
One use-case::
if filename.endswith(('jpg', 'gif', 'png')):
# ...
vs:
if (filename.endswith('jpg') or filename.endswith
('gif') or
filename.endswith('png')):
#...
Obviously it's not a huge improvement in clarity, but
it does seem to be an improvement to me.

FWIW, in Py2.5, this would be written:
if any(filename.startswith(s) for s in suffixes):

Logged In: YES user_id=80475 The previous comment was just information. I am +1 on the proposal because the use case is so common and the proposed form is concise, clear, and natural. |
