概述

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/env python3# -*- coding: utf-8 -*-
#温度转换

from graphics import *
 
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(2,5)
input.setText("0.0")
input.draw(win)
output = Text(Point(2,"")
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()
win.close()
