How do I slice dicts in Python safely and idiomatically?

In Python, dictionaries (dicts) are unordered collections of items, which means they do not support slicing in the same way that lists do. However, you can create a new dictionary that contains a subset of the original dictionary's key-value pairs using dictionary comprehensions or the `dict` constructor. This is a safe and idiomatic way to achieve dictionary slicing.

Example of Slicing a Dictionary


    original_dict = {'a': 1, 'b': 2, 'c': 3, 'd': 4}
    sliced_dict = {k: original_dict[k] for k in ['a', 'b'] if k in original_dict}
    print(sliced_dict)  # Output: {'a': 1, 'b': 2}
