python交互式图形编程实例（一）
本文实例为大家分享了python交互式图形编程的具体代码，供大家参考，具体内容如下
#!/usr/bin/envpython3#-*-coding:utf-8-*-
#温度转换
fromgraphicsimport*
win=GraphWin("摄氏温度转换器",400,300)
win.setCoords(0.0,0.0,3.0,4.0)
#绘制接口
Text(Point(1,3),"摄氏温度:").draw(win)
Text(Point(1,1),"华氏温度:").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),"转换")
button.draw(win)
Rectangle(Point(1,1.5),Point(2,2.5)).draw(win)
#等待鼠标点击
win.getMouse()
#转换输入
celsius=eval(input.getText())
fahrenheit=9.0/5.0*celsius+32.0
#显示输出，改变按钮
output.setText(fahrenheit)
button.setText("退出")
#等待响应鼠标点击，退出程序
win.getMouse()
