Bonjour Vincent!

Like this :

In[26]:=
Sort[{{something1, 3}, {something2, 1}, {something3, 7}, {something4, 2}},
  #1[[2]] < #2[[2]] & ]

Out[26]=
{{something2, 1}, {something4, 2}, {something1, 3}, {something3, 7}}

Meilleures salutations

Florian Jaccard

Hi,
I have a list of the form
{{something1,x1},{something2,x2},{something3,x3}} where x1,x2, x3 are
numbers. I want to sort this list with respect to xi. In other word if
x2<x3<x1 I want Mathematica to produce:
{{something2,x2},{something3,x3},{something1,x1}}
Thanks for your help
Vincent
