Sorting a List of Dictionaries in Python by Multiple Keys - Unexpected Order with Reverse Sorting
I'm refactoring my project and I'm reviewing some code and I keep running into I'm working on a personal project and I've looked through the documentation and I'm still confused about I'm trying to sort a list of dictionaries in Python by multiple keys, specifically by 'age' and 'name'. I want to sort by 'age' in ascending order and then by 'name' in descending order. However, I'm getting unexpected behavior with the sorted output, and the order of the names isn't as I expected. Here's the code I have so far: ```python people = [ {'name': 'Alice', 'age': 30}, {'name': 'Charlie', 'age': 30}, {'name': 'Bob', 'age': 25}, {'name': 'David', 'age': 25} ] sorted_people = sorted(people, key=lambda x: (x['age'], -ord(x['name'][0]))) print(sorted_people) ``` I thought using `-ord(x['name'][0])` would allow me to sort the names in descending order, but it doesn’t seem to be working as intended. I expected the output to be: ``` [ {'name': 'Bob', 'age': 25}, {'name': 'David', 'age': 25}, {'name': 'Alice', 'age': 30}, {'name': 'Charlie', 'age': 30} ] ``` Instead, the names are sorted in some random order. From the output, it seems like the sorting is not properly applying the descending sort for names. I've checked the Python version I'm using, which is 3.9.6, and I also confirmed that the `sorted` function should be able to handle tuples in the key. What am I missing here? Should I be using a different approach for sorting by a string in descending order? Any help would be greatly appreciated! Any ideas what could be causing this? This is for a desktop app running on Linux. Any feedback is welcome! What are your experiences with this? Any pointers in the right direction? The project is a application built with Python. I'm open to any suggestions.
