Question

Is there a more Pythonic way of doing this?:

            if self.name2info[name]['prereqs'] is None:
                self.name2info[name]['prereqs'] = []
            if self.name2info[name]['optionals'] is None:
                self.name2info[name]['optionals'] = []

The reason I do this is because I need to iterate over those later. They’re None to begin with sometimes because that’s the default value. It’s my workaround to not making [] a default value.

Thanks.

If you prefer this:

self.name2info[name]['prereqs'] = self.name2info[name]['prereqs'] or []
