Sometimes when you’re working with several different dictionaries, you need to group and manage them as a single one. In other situations, you can have multiple dictionaries representing different scopes or contexts and need to handle them as a single dictionary that allows you to access the underlying data following a given order or priority. In those cases, you can take advantage of Python’s ChainMap from the collections module. By Leodanis Pozo Ramos.
In this tutorial, you’ll learn how to:
- Create ChainMap instances in your Python programs
- Explore the differences between ChainMap and dict
- Use ChainMap to work with several dictionaries as one
- Manage key lookup priorities with ChainMap
Python’s ChainMap from the collections module provides an efficient tool for managing several dictionaries as a single one. This class is handy when you have multiple dictionaries representing different scopes or contexts and need to set access priorities to the underlying data. Good read!
