Need help solving a problem

If lower left is not always the lower left corner, make it so.

def point_in_rectangle(lower_left, upper_right, point):
    """Return True if point is in rectangle defined by corners lowerLeft
    and upper right.
    """
    llx = min(lower_left[0], upper_right[0])
    lly = min(lower_left[1], upper_right[1])
    urx = max(lower_left[0], upper_right[0])
    ury = max(lower_left[1], upper_right[1])
    x, y = point
    return llx <= x <= urx and lly <= y <= ury

But if you do that or not, use the Python way of comparing against a range, not the C way.

Do:
x1 <= test1 <= x2
Not
test1 >= x1 and test1 <= x2

If you really want to do a bunch of comparisons, do them using any():

def point_in_rectangle(lower_left, upper_right, point):
    """Return True if point is in rectangle defined by corners lowerLeft
    and upper right.
    """
    x1, y1 = lower_left
    x2, y2 = upper_right
    x, y = point

    return any((
        x1 <= x <= x2 and y1 <= y <= y2,
        x1 <= x <= x2 and y1 >= y >= y2,
        x1 >= x >= x2 and y1 <= y <= y2,
        x1 >= x >= x2 and y1 >= y >= y2))

print(point_in_rectangle((1, 2), (3, 4), (1.5, 3.2)))

See how easy it is to verify the logic when they are all aligned vertically like this?
