Sort a list in python

Question

I have this list

[1,-5,10,6,3,-4,-9]

But now I want the list to be sorted like this:

[10,-9,6,-5,-4,3,1]

Answer 1

Use abs as key to the sorted function or list.sort:

>>> lis = [1,-5,10,6,3,-4,-9]
>>> sorted(lis, key=abs, reverse=True)
[10, -9, 6, -5, -4, 3, 1]
