Question
Asked By – Hank Fay
I have a list of dictionaries like so:
[{'price': 99, 'barcode': '2342355'}, {'price': 88, 'barcode': '2345566'}]
I want to find the min() and max() prices. Now, I can sort this easily enough using a key with a lambda expression (as found in another Stack Overflow post), so if there is no other way I’m not stuck. However, from what I’ve seen there is almost always a direct way in Python, so this is an opportunity for me to learn a bit more.
Now we will see solution for issue: How to find the min/max value of a common key in a list of dicts?
Answer
lst = [{'price': 99, 'barcode': '2342355'}, {'price': 88, 'barcode': '2345566'}]
maxPricedItem = max(lst, key=lambda x:x['price'])
minPricedItem = min(lst, key=lambda x:x['price'])
This tells you not just what the max price is but also which item is most expensive.
