Python's ChainMap: Manage Multiple Contexts Effectively 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. ChainMap groups multiple dictionaries and mappings in a single, updatable view with dictionary-like behavior. Additionally, ChainMap provides features that allow you to efficiently manage various dictionaries, define key lookup priorities, and more.
