小栗子：修改温度转换程序
注意:color_rgb必须是int类型
#coding=gbk from graphics import * def convert(input): celsius = eval(input.getText()) # 输入转换 fahrenheit = 9.0/5.0 * celsius + 32 return fahrenheit def colorChange(win,input): cnum = eval(input.getText()) weight = cnum / 100.0 newcolor =color_rgb(int(255*weight),int(66+150*(1-weight)),int(255*(1-weight))) win.setBackground(newcolor) def main(): win = GraphWin("Celsius Converter", 400, 300) win.setCoords(0.0, 0.0, 3.0, 4.0) # 绘制输入接口 Text(Point(1,3), " Celsius Temperature:").draw(win) Text(Point(2,2.7), " (Please input 0.0-100.0 )").draw(win) Text(Point(1,1), "Fahrenheit Temperature:").draw(win) input = Entry(Point(2,3), 5) input.setText("0.0") input.draw(win) output = Text(Point(2,1),"") output.draw(win) button = Text(Point(1.5,2.0),"Convert It") button.draw(win) rect = Rectangle(Point(1,1.5), Point(2,2.5)) rect.draw(win) # 等待鼠标点击 win.getMouse() result = convert(input) # 转换输入 output.setText(result) # 显示输出 # 改变颜色 colorChange(win,input) # 改变按钮字体 button.setText("Quit") # 等待点击事件，退出程序 win.getMouse() win.close() main()
