兄弟们，
今天咱们试试用Python从文件中读取学生成绩，
并计算最高分/最低分/平均分。
涉及知识点
文件读写基础语法字符串处理循环遍历
代码展示
模块
import platform
定义获取最高分、最低分及平均分函数
python学习交流Q群：903971231###def compute_score():scores = []with open("./py023.txt", encoding="utf8") as fin:for line in fin:line = line.strip()fields = line.split(",")scores.append(int(fields[-1]))max_score = max(scores)min_score = min(scores)avg_score = round(sum(scores) / len(scores), 2)return max_score, min_score, avg_score
调用函数
max_score, min_score, avg_score = compute_score()print("最高分：" + str(max_score) +"\n" + "最低分：" + str(min_score) +"\n" + "平均分：" + str(avg_score))
