[python] Decrementing for loops

I want to have a for loop like so:

for counter in range(10,0):
       print counter,

and the output should be 10 9 8 7 6 5 4 3 2 1

This question is related to python for-loop decrement

The answer is


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

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


You need to give the range a -1 step

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

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]

range step should be -1

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