If an IRQ exception occurs, when other IRQ interrupts occur, the CPU will not respond; when an FIQ interrupt occurs, the current interrupt handling task will be stopped first to handle the FIQ interrupt, and then jump back to handle the IRQ interrupt. If an FIQ exception occurs, the proces...
except Exception as e: # Handle other exceptions finally: # Cleanup, runs no matter what 异常是按层次结构组织的,如果发生了IOError会执行IOError的except代码,剩下的异常则交由Exception处理。理解这个层次结构可以根据需要更广泛或更具体地捕获错误。 使用finally子句确保执行清理操作,而不管是否发生异常。它非常...

Python 通常被称为脚本语言,在信息安全领域占据主导地位,因为它具有低复杂性、无限的库和第三方模块。安全专家已经确定 Python 是一种用于开发信息安全工具包的语言,例如 w3af。模块化设计、易读的代码和完全开发的库套件使 Python 适合安全研究人员和专家编写脚本并构建安全测试工具。
Python considers these situations as exceptions and raises different kinds of errors depending on the type of exception. ValueError, TypeError, AttributeError, and SyntaxError are some examples for those exceptions. The good thing is that Python also provides ways to handle the exceptions. Consider ...
