REN`PY中怎么实现条件choice？

本来$符可以用来运行python代码，但是放在menu语句中就容易出错，包括if语句，又不想搞太多label费空间，求解。 define se = 1 menu choose: "选项主题" "choice1": "执行1内容" $ if se==1: "choice2": "执行2内容" 报错内容: Line is indented, but the preceding one-line python statement statement does not expect a block Please check this line's indentation You may have forgotten a coion()
