Python 中如何查看进行反汇编

dis模块

 

    Python 反汇编是通过 dis 这个模块来查看的，一般有两种方式可以用来查看

 

 

方式一： 在命令行中使用 dis 查看

 

>>> def test():
...     class X:
...             data = 100
...             def get(self): return self.data
...
>>>
>>>
>>> import dis
>>> dis.dis(test).  # 通过dis 模块查看汇编代码

              2 LOAD_CONST               1 (<code object X at 0x10b454ae0, file "<stdin>", line 2>)
              4 LOAD_CONST               2 ('X')
              6 MAKE_FUNCTION            0
              8 LOAD_CONST               2 ('X')
             10 CALL_FUNCTION            2
             12 STORE_FAST               0 (X)
             14 LOAD_CONST               0 (None)
             16 RETURN_VALUE
 
Disassembly of <code object X at 0x10b454ae0, file "<stdin>", line 2>:

              2 STORE_NAME               1 (__module__)
              4 LOAD_CONST               0 ('test.<locals>.X')
              6 STORE_NAME               2 (__qualname__)
 
  3           8 LOAD_CONST               1 (100)
             10 STORE_NAME               3 (data)
 
  4          12 LOAD_CONST               2 (<code object get at 0x10b454b70, file "<stdin>", line 4>)
             14 LOAD_CONST               3 ('test.<locals>.X.get')
             16 MAKE_FUNCTION            0
             18 STORE_NAME               4 (get)
             20 LOAD_CONST               4 (None)
             22 RETURN_VALUE
 
Disassembly of <code object get at 0x10b454b70, file "<stdin>", line 4>:

              2 LOAD_ATTR                0 (data)

方式二，通过运行 python 文件使用 -m 参数来查看
