Python Code Question

(10 pts) Write a boolean function, islnRect(t,xc,yc,W,H), which returns True if turtle, t, is inside or on the boundary of a rectangle of width, W, and height, H centered at xc,yc & which otherwise returns False. For this question and for the remainder of the test, assume that all rectangles have sides that are horizontal or vertical. 1. y axis (xc,yc) x axis x axis

Answer 1

import turtle

def isInRect(t,xc,yc,W,H):

    topLeftX = xc-W/2              # calculate the rectangle top left x value
    topLeftY=H/2+yc                # calculate the rectangle top left y value
    bottomRightX=xc+W/2            # calculate the rectangle bottom right x value
    bottomRightY=yc-H/2            # calculate the rectangle bottom right y value

    # return the below expression is True if turtle is inside the rectangle
    return topLeftX<=t.xcor() and t.xcor()<=bottomRightX and bottomRightY<=t.ycor() and t.ycor()<=topLeftY
