如何反编译pyc
uncompyle2 是一个可以将pyc文件转换为py源码的工具
下载地址：https://github.com/wibiti/uncompyle2
安装： setup.py install
参数：
|
Usage: uncompyle2 [OPTIONS]... [ FILE | DIR]...
Examples:
uncompyle2 foo.pyc bar.pyc # decompile foo.pyc, bar.pyc to stdout
uncompyle2 -o . foo.pyc bar.pyc # decompile to ./foo.dis and ./bar.dis
uncompyle2 -o /tmp /usr/lib/python1.5 # decompile whole library
Options:
-o <path> output decompiled files to this path:
if multiple input files are decompiled, the common prefix
is stripped from these names and the remainder appended to
<path>
uncompyle -o /tmp bla/fasel.pyc bla/foo.pyc
-> /tmp/fasel.dis, /tmp/foo.dis
uncompyle -o /tmp bla/fasel.pyc bar/foo.pyc
-> /tmp/bla/fasel.dis, /tmp/bar/foo.dis
-s if multiple input files are decompiled, the common prefix
is stripped from these names and the remainder appended to
<path>
uncompyle -o /tmp /usr/lib/python1.5
-> /tmp/smtplib.dis ... /tmp/lib-tk/FixTk.dis
-c <file> attempts a disassembly after compiling <file>
-d do not print timestamps
-m use multiprocessing
--py use '.py' extension for generated files
--norecur don't recurse directories looking for .pyc and .pyo files
--verify compare generated source with input byte-code
(requires -o)
--help show this message
Debugging Options:
--showasm -a include byte-code (disables --verify)
--showast -t include AST (abstract syntax tree) (disables --verify)
Extensions of generated files:
'.pyc_dis' '.pyo_dis' successfully decompiled (and verified if --verify)
'.py' with --py option
+ '_unverified' successfully decompile but --verify failed
+ '_failed' uncompyle failed (contact author for enhancement)

参数其实就是C:Python27Scriptsuncompyle2 文件里面， uncompyle2也是一个py文件但没有py扩展
代码如下：
1 #! /usr/bin/env python
2 import os
3 import sys
4
5 def displayFile(file):
6 unPath= sys.executable
7 unPath=unPath[ 0 : unPath.rfind( os.sep ) ]
8 newname = file[0:file.rfind('.')] + '.py'
9 command = "python -u "+unPath+"scriptsuncompyle2 " + file + ">" + newname
10 try:
11 os.system(command)
12 except e:
13 print file
14
15 if __name__ == '__main__':
16 print 'init'
17 displayFile('C:\pycc.pyc')
18 print 'finished'
经过测试 反编译后生成的py 执行报错：
SyntaxError： Non-ASCII character 'xd6' ***** but no encoding declared
一看就知道是编码问题， 说有在生成的py文件的头部加
# -*- coding: gbk -*-
很奇怪，# -*- coding: UTF8 -*- 也会报错
