替换open builtin [英] Replacing open builtin
问题描述
如果我更换open builtin例如
import main
__main __.__ builtins __。open = None
有没有办法，从这里开始，访问原来的开放功能？
稍微扩展一下，让我说我对原版进行了参考
在名为Isolate的类中打开函数并使用__getattribute__和__setattr__保护此引用
。原来的功能现在是隔离的吗？只能在隔离区内引用。
总之，除了
到__builtins__并且是__getattribute __，__ setattr__安全
问候

If I replace the open builtin eg
import main
__main__.__builtins__.open=None
Is there any way, from here on, to access the original open function??
Extending this slightly, lets say I put a reference to the original
open function inside a class called Isolate and protect this reference
using __getattribute__ and __setattr__. Is the original function now
isolated and only able to be referenced within Isolate.
In summary, are there any references to builtin functions others than
through __builtins__ and is __getattribute__, __setattr__ secure

推荐答案
有人可以推荐用于演示的Python交互式外壳吗？
理想特性（优先顺序）：
o可配置字体大小
o全屏模式
o readline支持
o语法着色
我我试过ipython但是，因为它在一个控制台窗口内运行，并且
控制台窗口的可选字体数量有限，所以它并不是很好的工作好吧。
我见过使用某种PyGame实现的shell的演示文稿。
有没有人有这方面的信息？
干杯，
Brian
Can anyone recommend a Python interactive shell for use in presentations?
Ideal characteristics (priority order):
o configurable font size
o full screen mode
o readline support
o syntax coloring
I''ve tried ipython but, since it runs inside a console window, and the
console window has a limited number of selectable fonts, it doesn''t
work terribly well.
I''ve seen presentations using some sort of PyGame implemented shell.
Does anyone have an information on that?
Cheers,

对不起，应该以__import__为例。
让我们说我抓取导入，将引用存储在Isolate类中
然后将内置导入重定向到Isolate类中的函数
只允许导入某些模块-eg不是系统。
这是安全的吗？
Sorry, should maybe have used __import__ as an example.
Let''s say I grab import, store the reference within the Isolate class
and then redirect the builtin import to a function in the Isolate class
which only allows certain modules to be imported -eg not sys. Would
this be secure?

嗯，您认为控制台窗口中的字体不可读吗？我已经在win32上使用ipython进行了几次演示，而且工作正常
- 但我认为投影机的质量是这里的一个因素......

Hmm, do you consider the fonts in a console window unreadable? I''ve
given a few presentations using ipython on win32 and it worked alright
- but I suppose the projector quality is a factor here...
