     except u.URLError as e:

This a because in Python 2 people sometimes write:

     except OSError, IOError:

thinking that it will catch both OSError and IOError.

except (OSError, IOError), e:  # Python 2.x

If you put them in a tuple, it will catch them, right?

In Python 2.x:

    except (OSError, IOError), e:

In Python 3.x (and also Python 2.6):

    except (OSError, IOError) as e:
