• RuntimeError

def ilove(name):
    if name=='陈培昌':
        print('i love {0}'.format(name))
    elif name == '程劲':
        print('i love {0}'.format(name))
    else:
        try:
            raise RuntimeError('who is he')
        except Exception as e:
            return e.args[0]
    return "这就是我的男神"

print(ilove('xxx'))

输出结果：

who is he

print(ilove('程劲')

输出结果：

i love 程劲
这就是我的男神

如果不把runtimeerror放入try catch中，则程序会因报错而中断

• 如果这样写，则执行结果会很不优雅

def ilove(name):
    if name=='陈培昌':
        print('i love {0}'.format(name))
    elif name == '程劲':
        print('i love {0}'.format(name))
    else:
        try:
            raise RuntimeError('who is he')
        except Exception as e:
            return e.args[0]
    print("这就是我的男神")

运行：print(ilove('程劲'))

输出结果：

i love 程劲
这就是我的男神
