Check out the range documentation, you have to define a negative step:

>>> range(10, 0, -1)
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]

You need to give the range a -1 step

 for i in range(10,0,-1):
    print i

for i in range(10,0,-1):
    print i,

The range() function will include the first value and exclude the second.

Could you please elaborate more your answer adding a little more description about the solution you provide? – abarisone Jun 30 '15 at 07:39
It's the same as for (let i = 10; i > 0; i--) { console.log(i); } @abarisone – wdev733 Oct 07 '22 at 18:43
