a. One coordinate is (130,130)Point b. One center is (30,40), radius 25 Pixel red outline of blue circle c. One side is 20 pixels, center point is (30,30), with 3 Pixel wide black outline of blue green square d. A bottom is at the point (100,200), length 100 a dark red line of pixels, with an upward pointing arrow at the top e. a width of 10, the height is 50, the center is (55,75Unfilled 'erected' oval f. One by point (7.5,7.5) centered, black outline of the orange hourglass g. one to (100,100) 'Hello World!' text centered in 16-point italics

3.次のインタラクティブグラフィックプログラムを実行するとどうなるかを説明します。

 1 from graphics import *  2  3 def main():  4 win = GraphWin()  5 shape = Circle(Point(50,50), 20)  6 shape.setOutline('red')  7 shape.setFill('red')  8  shape.draw(win)  9 for i in range(10): 10 p = win.getMouse() 11 c = shape.getCenter() 12 dx = p.getX() - c.getX() 13 dy = p.getY() - c.getY() 14  shape.move(dx,dy) 15  win.close() 16 main()

回答

The program draws a red circle with a center of (50, 50) and a radius of 20 pixels in the default graphics window, and then waits for the user to click the mouse 10 times. Each time the user clicks, the circle moves to the point of click (which is centered on it). After 10 clicks, the window disappears.

9、長方形の情報。

このプログラムは、ユーザーが描いた長方形に関する情報を表示します。
入力：長方形の対角線としてマウスを2回クリックします。
出力：長方形を描画します。
長方形の周囲と面積を印刷します。
式：面積=（長さ）（幅）
周囲長= 2（長さ+幅）

10.三角形の情報。
前の質問と同じですが、三角形の頂点は3回クリックされます。
式：周囲長については、線分の問題の長さを参照してください。

十一、 家を5回クリックします。

ユーザーがマウスを5回クリックするだけで簡単な家を描くことができるプログラムを作成します。最初の2回のクリックは、家の長方形のフレームの対角線です。 3回目のクリックは、長方形のドアの上端の中心を示します。ドアの幅は、家のフレームの幅の1/5にする必要があります。ドアの境界は、フレームの上部の角から下部まで伸びている必要があります。 4回目のクリックは、正方形のウィンドウの中心を示します。窓の幅はドアの半分です。最後のクリックは、屋根の頂点を示します。屋根の端は、家のフレームの頂点から上端の角まで伸びます。
