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 # 我还给大家准备了这些资料:Python视频教程、100本Python电子书、基础、爬虫、数据分析、web开发、机器学习、人工智能、面试题、Python学习路线图、问题解答! # 都放在这个扣群啦:279199867
定义获取最高分、最低分及平均分函数
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))
