Im trying to loop through perspective view and return a dictionary of parameters. Whats the best way to do it?  
Here is my pseudo code

parameterList = {}  
for param in view.custom.items():  
parameterList.insert({str(param [0]):param [1]})

`paramList = {key: self.custom[key] for key in self.custom}`

As long as we’re golfing…  
`return {k: v for k, v in self.custom.items()}`

Or, duh,  
`return dict(self.custom.items())`
