Question

Write the code in python only.

You will need the graphics library for this assignment. Please download the library and place it in the same file as your solution.

Draw a 12" ruler on the screen. A ruler is basically a rectangular outline with tick marks extending from the top edge. The tick marks should be drawn at each quarter-inch mark. Below the tick marks, your ruler should show large integers at each full-inch position.

Answer 1

from graphics import *

def main():
    win = GraphWin('Ruler', 1100, 350) # give title and dimensions

    rulerLen = 12
    eachInchLen = 80
    xStart = 70

    rect = Rectangle(Point(xStart - 10, 50), Point(10 + xStart + rulerLen * eachInchLen, 100))
    rect.setFill("yellow")
    rect.draw(win)

    for i in range(13):
        xS = xStart + i*eachInchLen

        l = Line(Point(xS, 50), Point(xS, 75))  # set endpoints
        l.setWidth(2)
        l.draw(win)

        label = Text(Point(xS, 90), str(i))
        label.draw(win)

        if i != 12:
            xS = xStart + i*eachInchLen + eachInchLen/2
            l = Line(Point(xS, 50), Point(xS, 70))  # set endpoints
            l.setWidth(1)
            l.draw(win)

            xS = xStart + i*eachInchLen + eachInchLen/4
            l = Line(Point(xS, 50), Point(xS, 60))  # set endpoints
            l.setWidth(1)
            l.draw(win)

            xS = xStart + i*eachInchLen + 3*eachInchLen/4
            l = Line(Point(xS, 50), Point(xS, 60))  # set endpoints
            l.setWidth(1)
            l.draw(win)

    win.getMouse()
    win.close()

main()
