Unexpected behavior with dict comprehensions in Python 3.10 when merging dictionaries
I've been struggling with this for a few days now and could really use some help... Quick question that's been bugging me - I'm experiencing unexpected behavior when using dictionary comprehensions in Python 3.10 for merging two dictionaries. I have two dictionaries, `dict_a` and `dict_b`, and I want to create a new dictionary that merges them, prioritizing the values from `dict_b` when there are key collisions. Here’s the code I’m using: ```python dict_a = {'a': 1, 'b': 2, 'c': 3} dict_b = {'b': 3, 'c': 4, 'd': 5} merged_dict = {k: v for d in (dict_a, dict_b) for k, v in d.items()} ``` However, the `merged_dict` I get is: ```python {'a': 1, 'b': 2, 'c': 3, 'd': 5} ``` Instead of getting `{'a': 1, 'b': 3, 'c': 4, 'd': 5}` where values from `dict_b` should override those from `dict_a`. I've also tried using the `|` operator to merge dictionaries: ```python merged_dict = dict_a | dict_b ``` But this works correctly and gives me the expected output. I thought my comprehension approach would also work similarly. Is there a specific reason why my dictionary comprehension is not behaving as expected? Are there any best practices to keep in mind when using comprehensions for merging dictionaries in Python? Any insights into this behavior would be appreciated! My development environment is Windows. I'd really appreciate any guidance on this. Am I missing something obvious? I'm working in a Linux environment. Thanks for any help you can provide!
