Scoped change of a global variable

[Steven Majewski]

[ To follow myself up ] ... but the more Pythonic solution
would probably be to avoid using global values for defaults
and to use a class instead:


>>> class NameSpace:
...     default = 1
...     def __init__( self, **kws ):
...             for key,value in kws.items():
...                     setattr( self, key, value )
...     def __call__( self, n ):
...             print n + self.default
...
>>> NameSpace.default
1
>>> NameSpace()(2)
3
>>> NameSpace( default=100 )(2)
102
>>> NameSpace.default
1
>>>
