How do I read a dictionary key that might be missing?
Faculty
Use dictionary.get(key, default) when a missing key is expected and you have a sensible default.
Student 2
What if None is a valid value for that key?
Faculty
Check key in dictionary first if you need to distinguish a missing key from a key whose value is None.
