What is the outcome of using from collections import defaultdict?

Using "from collections import defaultdict" specifically imports the defaultdict class from the collections module into the current namespace. This allows you to use defaultdict directly without needing to prefix it with "collections."

The defaultdict class is a subclass of the built-in dict class, and it overrides one method to provide a default value for a nonexistent key. This is particularly useful for creating dictionaries that need to handle missing keys gracefully.

When you perform the import in this way, you are not importing the entire collections module, which would include all of its components. Nor are you exporting or deleting any functions; the import statement merely makes defaultdict available in your code for immediate use. This focused import is efficient and helps keep the namespace clean.
