Pip 是安装python包的工具，提供了安装包，列出已经安装的包，升级包以及卸载包的功能。
Pip 是对easy_install的取代，提供了和easy_install相同的查找包的功能，因此可以使用easy_install安装的包也同样可以使用pip进行安装。

将在codeskulptor 的代码本地保存为一个.py的文件，将import simplegui
改为：import SimpleGUICS2Pygame.simpleguics2pygame as simplegui
在命令行中运行本地脚本python test.py
然后就能在本地操作codeskulptor 上的游戏了。就不用连到服务器操作。
File "/Users/rainvoo/pythoncamp0/source/part2/guesslocal.py", line 7 SyntaxError: Non-ASCII character '\xe5' in file /Users/rainvoo/pythoncamp0/source/part2/guesslocal.py on line 7, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details [Finished in 0.1s with exit code 1]
解释：
有时候，在 Python 脚本里有中文的时候，会报下面的错误：
Non-ASCII character '\xe5' in file ……
原因：Python 默认是以 ASCII 作为编码方式的，如果在自己的 Python 源码中包含了中文（或者其他非英语系的语言），此时即使你把自己编写的 Python 源文件以 UTF-8 格式保存了，但实际上，这依然是不行的。
解决办法很简单，只要在文件开头加入下面代码就行了。
# -*- coding: UTF-8 -*- 或 #coding=utf-8
注：此语句一定要添加在源代码的第一行。
几个概念要先搞清楚：
默认的python文件是采用ascii编码的，在头部加入 # -*- coding: utf-8 -*- 则指定文件的编码格式是 utf-8，那么就是说文件内你可以用中文或其他的文字了。
cn = u"中文"，这个前缀 u 代表“中文”是采用 unicode 编码，也就是 cn 并不是 string 而是一个 unicode。
当你用 print 输出的时候会自动根据本地的语言环境转换成 string。

import SimpleGUICS2Pygame.simpleguics2pygame as simplegui File "/Library/Python/2.7/site-packages/SimpleGUICS2Pygame/simpleguics2pygame.py", line 59, in
import pygame.font ImportError: No module named font
解释：
执行的py文档导入了SimpleGUICS2Pygame.simpleguics2pygame，但是导入的模块中，第59行为import pygame.font，而本地环境中无此模块儿，导致运行失败。
待续。。。
