[Tutor] A range of numbers

[Gregor Lingl]

Hi Leung!

There is a range function in Python:

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

It outputs lists of integer values.
play around with it to learn how it works.
(Even to call range(10,20,2), i. e. with
3 arguments, is possible)

On the other han you can check if some value
is in a certain range with the in - Operator:

>>> y = 4
>>> y in range(5)
True # 1 in older Versions of Python
>>> y in range(5,10)
False # or 0

so if you first extract the coordinates of
your mouse-position:

>>> x,y = mouse_position()

then you can easily check if y is in the desired
range.
