Solve the following python programming problem given the following code:
def WrappedCommandFactory(wrapped, default_kwargs = None) : 
    base_kwargs = { 
        
} 
    base_kwargs.update (DEFAULT_COMMAND_KWARGS) 
    if (base_kwargs is not None) : 
        base_kwargs.update (default_kwargs) 
class WrappedCommand (object) : 
        '
        Wraps a Django management command
        ' 
        def __init__(self, site) : 
            self.site = site 
def execute(self) : 
            kwargs = { 
                'locale' : self.site.locale, 
} 
            kwargs.update (base_kwargs) 
            cmd = wrapped () 
            with chdir (self.site.path) : 
                cmd.execute (** kwargs) 
return WrappedCommand
