python怎样进行反编译

1、使用第三方库uncompyle

这个库可以将代码反编译成字节码指令和源代码

（推荐教程：Python入门教程）

举例：

from uncompyle2 import *
fp = open("code.txt","wb")
uncompyle_file('test.pyc',fp,showasm=1,showast=0)
fp.close()

2、使用python自带的dis模块

>>> import dis
>>> def inplace_add():
...     a = 0
...     a += 1
... 
>>> def add_and_assign():
...     a = 0
...     a = a + 1
... 
>>> dis.dis(inplace_add)
  2           0 LOAD_CONST               1 (0)
              3 STORE_FAST               0 (a)
 
  3           6 LOAD_FAST                0 (a)
              9 LOAD_CONST               2 (1)
             12 INPLACE_ADD         
             13 STORE_FAST               0 (a)
             16 LOAD_CONST               0 (None)
             19 RETURN_VALUE        
>>> dis.dis(add_and_assign)
  2           0 LOAD_CONST               1 (0)
              3 STORE_FAST               0 (a)
 
  3           6 LOAD_FAST                0 (a)
              9 LOAD_CONST               2 (1)
             12 BINARY_ADD          
             13 STORE_FAST               0 (a)
             16 LOAD_CONST               0 (None)
             19 RETURN_VALUE
