回溯3次点击房屋代码

Question

我是python的新手，我得到了一个无效的语法(参见下面的错误)，我不擅长这个error....help？我正在编写代码，在4个点击建造一所房子。下面的很多代码都是我尝试不同的东西，所以忽略它(或者给我应该做什么的建议)，这是p2错误让我困惑的地方。

<using graphics.py>
import graphics
from graphics import*

def house():
    win=GraphWin(800,500)
    win.setCoords(0.0,0.0,4.0,4.0)#reset coordinates
    Text(Point(2.0,3.5),"click spot to designate 2 corners of house").draw(win)
    p1=win.getMouse()
    p1.draw(win)
    side1=(Point(p1.getX(),(p1.getY()))
    p2=win.getMouse()<----------------------------ERROR with the p2
    p2.draw(win) 
    side2=(Point(p2.getX(),(p2.getY()))
    rect = Rectangle(side1,side2)
    rect.draw(win)

    #door- p3=center top edge of door
    msg2 = Text(Point(2.0,0.5),"click to designate top of door")
    msg2.draw(win)
    p3=win.getMouse()
    p3.draw(win)
    #golden:)
    Line(Point(p3.getX(),(p3.getY())),(Point(p2.getX()),(p2.getY()))).draw(win)
    """
    p3 = dwidth.getCenter()                             
    rectWidth = (p2.getX()) - (p1.getX())
    #doorWidth = door.setWidth(distance/5.0)#width 1/5 of house 
    dwidth= eval((rectWidth) / (5))
    dheight=((getP3(),(getP2()))#height = from top corners to bottom of the frame
    #door = Rectangle((dwidth) * (dheight))"""
    #door.draw(win)

    """#Window
    message3 = Text(Point(2.0, 1.0),"click to designate center of square     window").draw(win)
    p4=win.getMouse()
    p4.draw(win)
    c=door.getCenter()
    dx=p4.getX()-c.getX()
    dy=p4.getY()-c.getY()
    window = Rectangle(Point(dx,dx),Point(dy,dy))
    window.draw(win)

    #window.draw(win)
house()

Answer 1

之所以会出现这个错误，是因为Point需要一个x和一个y参数，而您只在尝试创建x的那一行中传递了一个Rectangle。

不是很确定你的代码想要做什么，但希望这能帮助你朝着正确的方向开始：

from graphics import *

def house():
    win=GraphWin(800,500)
    win.setCoords(0.0,0.0,3.0,4.0)#reset coordinates
    Text(Point(1.5,3.5),"click spot to designate 2 corners of house").draw(win)
    p1 = win.getMouse()
    p1.draw(win)
    p2 = win.getMouse()
    p2.draw(win)
    rectangle = Rectangle(p1, p2)
    rectangle.setWidth(3)
    rectangle.draw(win)
    win.getMouse()
    win.close()

house()
