Decrementing for loops [duplicate]

a = " ".join(str(i) for i in range(10, 0, -1))
print (a)

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.

range step should be -1

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