Python程序开发之简单小程序实例（11）小游戏-跳动的小球

Python程序开发之简单小程序实例

（11）小 游戏 -跳动的小球

一、项目功能

用户控制挡板来阻挡跳动的小球。

二、项目分析

根据项目功能自定义两个类，一个用于控制小球在窗体中的运动，一个用于接收用户按下左右键时，挡板在窗体中的运动。在控制小球的类中，我们还需要考虑当小球下降时，碰到挡板时的位置判断。

三、程序源代码

源码部分截图：

源码：

#!/usr/bin/python3.6

# -*- coding: GBK -*-

#导入相应模块

from tkinter import *

import random

import time

#自定义小球的类 Ball

class Ball:

# 初始化

def __init__(self,canvas,paddle,color):

#传递画布值

self.canvas=canvas

#传递挡板值

self.paddle=paddle

#画圆并且保存其ID

self.id=canvas.create_oval(10,10,25,25,fill=color)

self.canvas.move(self.id,245,100)

#小球的水平位置起始列表

start=[-3,-2,-1,1,2,3]

#随机化位置列表

random.shuffle(start)

self.x=start[0]

self.y=-2

self.canvas_heigh=self.canvas.winfo_height()#获取窗口高度并保存

self.canvas_width=self.canvas.winfo_width()

#根据参数值绘制小球

def draw(self):

self.canvas.move(self.id,self.x,self.y)

pos=self.canvas.coords(self.id)#返回相应ID代表的图形的当前坐标（左上角和右上角坐标）

#使得小球不会超出窗口

pad=self.canvas.coords(self.paddle.id)#获取小球挡板的坐标

if pos[1]=self.canvas_heigh or(pos[3]=pad[1] and pos[2]=pad[0] and pos[2]

python编程例子有哪些？

python编程经典例子：

1、画爱心表白、图形都是由一系列的点(X，Y)构成的曲线，由于X，Y满足一定的关系，所以就可以建立模型，建立表达式expression，当满足时，两个for循环（for X in range；for Y in range）就会每行每列的打印。

2、快递查询工具、此Python小项目需要用到json与requests两个库，还需调用API。

3、用python编程完成图像识别、鼠标模拟，需要调用OpenCV框架。

扩展资料：

Python的设计目标之一是让代码具备高度的可阅读性。它设计时尽量使用其它语言经常使用的标点符号和英文单字，让代码看起来整洁美观。它不像其他的静态语言如C、Pascal那样需要重复书写声明语句，也不像它们的语法那样经常有特殊情况和意外。

Python开发者有意让违反了缩进规则的程序不能通过编译，以此来强制程序员养成良好的编程习惯。并且Python语言利用缩进表示语句块的开始和退出，而非使用花括号或者某种关键字。增加缩进表示语句块的开始，而减少缩进则表示语句块的退出，缩进成为了语法的一部分。

python编程问题？

可以使用 Python 的 itertools 模块来生成所有可能的组合，然后再计算每个组合的和。以下是示例代码：

在此代码中，我们首先使用 itertools.combinations() 函数生成了所有可能的组合，并将它们存储在一个名为 combinations 的列表中。然后，我们对列表中的每个组合求和，将它们存储在另一个名为 sums 的列表中。最后，我们通过将 sums 转换为一个集合来确定唯一的和，并打印出我们找到的所有唯一和的数量以及它们各自的值。

请注意，如果数字非常多或者复杂度高，则可能需要考虑优化该代码，以便更有效地生成和计算组合的和。
