with open('./score.txt', 'r') as f: lines = f.readlines() scores = [] for line in lines: scorelist = line.strip().split(',')[1:] scoreint = [int(score) for score in scorelist] scores.append(scoreint) for i in range(3): playerscore = [] for grade in scores: playerscore.append(grade[i]) maxplayerscore = max(playerscore) minplayerscore = min(playerscore) playerscore.remove(maxplayerscore) playerscore.remove(minplayerscore) avgscore = sum(playerscore) / len(playerscore) chosenone=max(avgscore) print(chosenone)

这段代码中有语法错误，需要先对代码进行修正。以下是修正后的代码：

with open('./score.txt', 'r') as f:
    lines = f.readlines()
    scores = []
    for line in lines:
        scorelist = line.strip().split(',')[1:]
        scoreint = [int(score) for score in scorelist]
        scores.append(scoreint)
    avgscores = []
    for i in range(3):
        playerscore = []
        for grade in scores:
            playerscore.append(grade[i])
        maxplayerscore = max(playerscore)
        minplayerscore = min(playerscore)
        playerscore.remove(maxplayerscore)
        playerscore.remove(minplayerscore)
        avgscore = sum(playerscore) / len(playerscore)
        avgscores.append(avgscore)
    chosenone = max(avgscores)
    print(chosenone)

这段代码从文件中读取学生成绩，计算每门课程的平均分，然后输出平均分最高的课程的平均分。
