Python – Sort Tuples Python

pythonsortingtuples

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!

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 ..

The sorted() function takes a key= parameter

newlist = sorted(list_to_be_sorted, key=lambda d: d['name'])

Alternatively, you can use operator.itemgetter instead of defining the function yourself

from operator import itemgetter
newlist = sorted(list_to_be_sorted, key=itemgetter('name'))

For completeness, add reverse=True to sort in descending order

newlist = sorted(list_to_be_sorted, key=itemgetter('name'), reverse=True)

Python – How to execute a program or call a system command

Use the subprocess module in the standard library:

import subprocess
subprocess.run(["ls", "-l"])

The advantage of subprocess.run over os.system is that it is more flexible (you can get the stdout, stderr, the "real" status code, better error handling, etc...).

Even the documentation for os.system recommends using subprocess instead:

The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. See the Replacing Older Functions with the subprocess Module section in the subprocess documentation for some helpful recipes.

On Python 3.4 and earlier, use subprocess.call instead of .run:

subprocess.call(["ls", "-l"])
