扑获异常 1.1 基本语法 把可能抛出异常(出错)的语句放在try的block里，然后用except去扑捉(预判)可能的异常类型，如果异常类型match，就执行except模块。...f.read() f.close() except IOError: print 'file not found' file not found 执行流程是这样的： First statement...between try and except block are executed....If file don’t exists then exception will be raised and the rest of the code in the try block will be...else只有在try执行时没有异常的时候执行。 finally不管try模块是否有异常抛出，都执行。
