get(key, default=None, type=None)¶
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
ValueErrorif 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
- key – The key to be looked up.
- default – The default value to be returned if the key can’t be looked up. If not further specified None is returned.
- type – A callable that is used to cast the value in the
MultiDict. If a
ValueErroris raised by this callable the default value is returned.
