Decrementing With range()

You can supply a negative step value to generate a list of numbers that is decreasing. If you do that, you need to make sure your stopping value is less than your starting value, or else you’ll get a list with no elements:

for i in range(10, -6, -2):
    print(i)

This will start at 10 and count down by 2 until you reach -6, or rather -4 because you don’t include -6.
