你可以将函数sumx()中的最后一个for循环改为以下代码：

for i, row in enumerate(data):
    row.append(str(new2[i]))
    data[i] = row

这段代码可以将每个人的总分添加到其成绩后面，然后将修改后的data列表输出即可。最终的sumx()函数代码如下：

def sumx():
    with open("C:\\Users\\ASUS\\Desktop\\student.txt", "r", encoding="UTF-8") as f:
        content=f.readlines()
        new = [content[i] for i in range(2,len(content),2)]
        new = [i[:-1] for i in new]
        new = [i.split() for i in new]
        new2 = list()
        for i in new:
            new1 = list()
            for j in range(2,len(i)):
                new1.append(int(i[j]))
            tmp = sum(new1)
            new2.append(tmp)
        
    with open("C:\\Users\\ASUS\\Desktop\\student.txt", "r", encoding="UTF-8") as f:
        content=f.readlines()
        header = content[0].split()
        a=int(input("请输入您的选择(1-3)"))
        data = [line.split() for line in content[1:]]
        data = data[1:]
        for i, row in enumerate(data):
            row.append(str(new2[i]))
            data[i] = row
        for i in data:
            print('\t'.join(i))

注意在输出时需要使用制表符('\t')将每个字段隔开。
