python: error handling RFresh 把每一件事都当作最后一件事来做LBYL: Look Before You Leap 出错之前检查数值是否在范围内,如果不在,定制自己的出错信息 EAFP: Easier to Ask Forgiveness than Permisson: 不需要提前检查数值确认是否在范围之内,出错后用try...except 来处理。
Exception as error: 这里指定的异常事件是 Exception 类,抓住了之后给其定义一个变量叫 error, 然后进入异常处理。 # error handling: 这里是抓住了异常事件之后做处理。 finally: 这是可有可无的,不论异常有没有出现被抓住,都会进入这个语法,一般是用来做数据清理,并且保证可以被执行的一段话。 Python的异常处理...

except_suite# exception-handling code 异常处理代码 在程序运行时, 解释器尝试执行 try 块里的所有代码, 如果代码块完成后没有异常发生, 执行流就会忽略 except 语句继续执行. 而当 except 语句所指定的异常发生后, 我们保存了错误的原因, 控制流立即跳转到对应的处理器( try 子句的剩余语句将被忽略)。
