pyc(pyo)文件反编译:depython

DePython是什么?

DePython是用来反编译经过python编译的后缀名为pyc或pyo的字节码文件的.
如果你找不到你写的python源代码，Depython可以帮助你通过pyc/pyo文件来找回这些源代码。 经DePython反编译得出的python源代码，和你原来的代码文件几乎完全一样。

DePython支持那些版本的Python?

Depython支持很多Pythond的版本，甚至是最新的Python2.5。

用发送天气邮件 试了下，得到的结果还是非常相似的(除了将汉字用utf8编码)

有空去研究下这个怎么实现的，太强了也～～
