How to count and order numbers in a list

[rachyioli]

Hi guys, I have a list of random numbers and I want to know how many times each number occurs on the list ; I want them ordered by the ones that occurred the most first.
This is my program :

lex=(1,2,3,4,5,6,1,2,3,3,3)
x=0
for i in range(7):
	print(x," appeared  ", lex.count(i))
	x+=1

and this is what I get :

Output:
0  is  0
1  is  2
2  is  2
3  is  4
4  is  1
5  is  1
6  is  1

what I need now is to order them from the ones that happened the most in the list: In this case 3 should be at the top because it happened four times ...
is there a way I can use two functions at the same time in this loop.
thanks
