For your current situation, list(os.environ) or iter(os.environ) both return keys only. It looks like the __repr__ on the class for os.environ is printed for os.environ (which is expected). For os.environ.keys(), the same __repr__ is wrapped as a KeysView, for os.environ.values(), it's wrapped as a ValuesView, and os.environ.items(), as an ItemsView. In 2.7, os.environ.keys() print just keys.
