def get (self, key, default=None, type=None)
 

Detailed Description

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.

Member Function Documentation

◆ get()

def get (   self,
  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 :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.
