如果你的class不是container,你可以实现__nonzero__方法,如下: class MyClass(object): def __init__(self, value): self.value = value def __nonzero__(self): """ Return my truth value (True or False). """ # This could be arbitrarily complex: return bool(self.value) 在Python 3.x中,...
使用 Capstone 和 PyDBG 呈现了调试技术。 第七章,“Crypto, Hash, and Conversion Functions”,总结了 Python 密码工具包,帮助您编写脚本来查找不同类型的密码哈希。 第八章,“Keylogging and Screen Grabbing”,讨论了键盘记录和屏幕截图技术的基础。这些技术是使用 PyHook 呈现的,它可以帮助使用 Python 记录键盘事...

ctypes.CFUNCTYPE(restype, *argtypes, use_errno=False, use_last_error=False)The returned function prototype creates functions that use the standard C calling convention. The function will release the GIL during the call. If use_errno is set to true, the ctypes private copy of the system errno...
Python是解释型语言,没有严格意义上的编译和汇编过程。但是一般可以认为编写好的python源文件,由python解释器翻译成以.pyc为结尾的字节码文件。pyc文件是二进制文件,可以由python虚拟机直接运行。 Python在执行import语句时,将会到已设定的path中寻找对应的模块。并且把对应的模块编译成相应的PyCodeObject中间结果,然后创建...
