异常处理

Except 后面可以捕捉任何异常，大写英文字母开头。。。

 

first = input(‘请输入除数：‘)
second = input(‘请输入被除数：‘)
try:
    first = int(first)
    second = int(second)
    res = first/second
                    except ValueError as e:   #这个e代表错误信息
                        print(e)
                        print(‘请输入整数‘)
                    except ZeroDivisionError as e:
                        print(‘除数不能为0‘)
except Exception as e:     #上面代码出异常的时候走这里
    print(e)
    print(‘出错异常‘)
else:               #没有出错
    print(‘并没有出错‘)
finally:
    print(‘最后结局‘)
