[Tutor] check_range

[Kent Johnson]

You misunderstand what range() does. It returns a list of numbers starting with the lower one and up 
to but not including the upper one:
 >>> range(5)
[0, 1, 2, 3, 4]
 >>> range(5, 10)
[5, 6, 7, 8, 9]

To test for a number in a range you can use 10 < n < 90:
 >>> x = 1
 >>> 10 < x < 90
False
 >>> x = 15
 >>> 10 < x < 90
True
 >>> x = 100
 >>> 10 < x < 90
False
