How does defaultdict work? (Duplicate 2)

  • defaultdict will automatically create a dictionary for you that has keys which are the integers 0-10.
  • defaultdict forces a dictionary to only accept keys that are of the types specified when you created the defaultdict (such as strings or integers).
  • If you try to read from a defaultdict with a nonexistent key, a new default key-value pair will be created for you instead of throwing a KeyError.
  • defaultdict stores a copy of a dictionary in memory that you can default to if the original gets unintentionally modified.
