该代码段展示了如何使用Python处理一个包含学号、姓名及三门成绩的学生成绩列表。首先，定义了头信息，然后通过循环计算每个学生的总分和平均分，并将这些信息追加到原始数据中。最后，将处理后的数据以逗号分隔的形式写入到名为'std.txt'的文件中，实现了文件读写操作。

scores=[
    ["001","李明",92.5,93,94],

    ["003","李硕",94.5,93,88],
    ["004","李东",86.5,81,87],

print(scores)
head=["学号","姓名","语文","数学","总分","平均分"]
with open("std.txt","w")   as fs:
    fs.write(",".join(head)+"\n")    #把head以逗号分隔的字符串，写入文件,如果列表内有数字，则写入失败
    for student in scores:
        total = 0
        for j in range(2,5):
            total +=student[j]
        student.append(total)
        student.append(int(total/3))
        #print(student)
        for y in student:
            fs.write(str(y)+" ")
        fs.write("\n ")
