How do I merge dicts in Python in a memory-efficient way?

In Python, merging dictionaries can be done in various ways, but if you're looking for a memory-efficient method, consider using a generator expression or the `collections.ChainMap` class. This approach allows you to merge dictionaries without creating intermediate copies, thus using less memory.

Example of Merging Dictionaries using ChainMap


        from collections import ChainMap

        dict1 = {'a': 1, 'b': 2}
        dict2 = {'b': 3, 'c': 4}

        merged_dict = dict(ChainMap(dict2, dict1))
        print(merged_dict)  # Output: {'b': 3, 'c': 4, 'a': 1}
