How does defaultdict work?
- defaultdict will automatically create a dictionary for you that has keys which are the integers 0-10.
- If you try to access a key in a diction that doesn’t exist, defaultdict will create a new key for you instead of throwing a KeyError.
- defaultdict forces a dictionary to only accept keys that are the data type specified when you created the defaultdict.
- defaultdict stores a copy of a dictionary in memory that you can default to if the original gets unintentionally modified.
