The Python defaultdict
type is a dictionary-like data structure provided by the Python standard library in a module called collections
. The class inherits from dict
, and its main added functionality is to supply default values for missing keys. In this course, you’ve learned how to use the Python defaultdict
type for handling the missing keys in a dictionary.
You’re now able to:
- Create and use a Python
defaultdict
to handle missing keys - Solve real-world problems related to grouping, counting, and accumulating operations
- Know the implementation differences between
defaultdict
anddict
- Decide when and why to use a Python
defaultdict
rather than a standarddict
