A little house

Task

Draw a little house: a square body (create_rectangle) and above it a triangular roof (create_polygon or create_line). The roof's base is the top corners of the square and its tip is above the house.

The program runs in a tkinter simulation right in your browser - after Run you see the window and can click it. The tests click and check what was drawn on the canvas.

Examples

Call

from tkinter import _mente as okno

stvorce = [r for r in okno.items("rectangle")
           if abs(abs(r.coords[2] - r.coords[0]) - abs(r.coords[3] - r.coords[1])) < 1]
okno.check("dom ma stvorcove telo", len(stvorce) >= 1)
if stvorce:
    s = stvorce[0]
    lavy, pravy = sorted([s.coords[0], s.coords[2]])
    horny = min(s.coords[1], s.coords[3])
    body = [(round(x), round(y)) for i in okno.items() if i.kind in ("line", "polygon")
            for x, y in zip(i.coords[0::2], i.coords[1::2])]
    okno.check("strecha zacina v hornych rohoch", (round(lavy), round(horny)) in body and (round(pravy), round(horny)) in body)
    okno.check("strecha ma vrchol nad domom", any(lavy < x < pravy and y < horny for x, y in body))

Expected output

dom ma stvorcove telo: OK
strecha zacina v hornych rohoch: OK
strecha ma vrchol nad domom: OK

Python starts the first time you run code.

Try it yourself first. Each hint reveals a little more - and lowers the reward a little.
