Python

list = list.sort()

I know the proper way to sort a list is just doing list.sort(), but I was wondering what is happening behind the scenes when you try to do something like list = list.sort()

When I do that and try to print list, I just get 'None' and I'm just curious what is happening for that to happen.

The "sort" method sorts the list, but doesn't return anything (so "None").
But there's another method you could use that does return the sorted list (instead of changing it directly):

list = list.sorted()
