def | get (self, key, default=None, type=None) |
Works like a regular dict but the :meth:`get` method can perform type conversions. :class:`MultiDict` and :class:`CombinedMultiDict` are subclasses of this class and provide the same feature. .. versionadded:: 0.5

Return the default value if the requested data doesn't exist. If `type` is provided and is a callable it should convert the value, return it or raise a :exc:`ValueError` if that is not possible. In this case the function will return the default as if the value was not found: >>> d = TypeConversionDict(foo='42', bar='blub') >>> d.get('foo', type=int) 42 >>> d.get('bar', -1, type=int) -1 :param key: The key to be looked up. :param default: The default value to be returned if the key can't be looked up. If not further specified `None` is returned. :param type: A callable that is used to cast the value in the :class:`MultiDict`. If a :exc:`ValueError` is raised by this callable the default value is returned.
Reimplemented in CombinedMultiDict.
