    ["小A","女",21,"大一"],

    ["小B","男",23,"大三"],

    ["小C","男",24,"大四"],

    ["小D","女",21,"大一"],

    ["小E","女",22,"大四"],

    ["小F","男",21,"大一"],

    ["小G","女",22,"大二"],

    ["小H","女",20,"大三"],

    ["小I","女",20,"大一"],

    ["小J","男",20,"大三"],

    在每个数组后面加个逗号表示连贯性,不然就会报错

    这个代码里的姓名,性别和年级都要用双引号,你定义的时候用的是单引号,改一下,对了请采纳,错了发改过的代码,我再帮你改改
