collections.ChainMap — a built-in Python class that combines multiple dictionaries or other mappings into a single, updatable view. 🧠

Instead of merging dictionaries and creating new data structures in memory, it links them by reference, allowing you to search and manage them as a single entity. 🔗

# Example usage of collections.ChainMap
from collections import ChainMap

dict1 = {'a': 1, 'b': 2}
dict2 = {'b': 3, 'c': 4}
combined = ChainMap(dict1, dict2)
print(combined['b'])  # Output: 2
