I have a list of tuples in my Blender python code
scores=[(1489,"Sean"), (2850,"Bob"), (276,"Crap Player"), (78495, "Great Player"), (8473, "Damian"), (4860, "Andy"), (0, "Stephen")]
I'm trying to sort them by their score by using this
sorted(scores, key=lambda score: score[0], reverse=True)
but this is not working. I have no idea why. Any tips?
I've considered maybe a better implementation is to create a new Score class with fields name and score
EDIT:
Thanks guys for the fast reply
it was giving me no errors with the sorted method but was not sorting.
I used the sort() and it works.
I think python is just a little weird in Blender maybe?
Thanks!

In Python, there are two ways, sort() and sorted() , to sort lists ( list ) in ascending or descending order. If you want to sort strings ( str ) or tuples ( tuple ), use sorted() .
To sort elements of a tuple, we can use the sorted function, providing the tuple as the first argument. This function returns a sorted list from the given iterable, and we can easily convert this list into a tuple using the built-in function tuple. We can use the two optional parameters (key and reverse) as well.
In python, to sort list of tuples by the first element in descending order, we have to use the sort() method with the parameter ” (reverse=True) “ which will sort the elements in descending order.
You can use one of the easiest sorting algorithm that is bubble sort. In case of tuples in tuple it will sort in order of first element of tuple. So ((32, "b"), (1, "c"), (23,"a")) Now if you sort it it will sort it in the order of 1st element of tuple.
Just do:
print sorted(scores, reverse=True)
[(78495, 'Great Player'), (8473, 'Damian'), (4860, 'Andy'), (2850, 'Bob'), (1489, 'Sean'), (276, 'Crap Player'), (0, 'Stephen')]
you can use scores.sort(reverse=True) if you want to sort in place, and by the way the sort function in case of list of tuple by default sort by first item , second item ..

sorted() returns the sorted sequence. If you want to sort a list in place then use list.sort().
