用Python从文件中读取学生成绩，并计算最高分/最低分/平均分
|
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 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))全部代码 import platform print("待到红旗满天下,马踏东京赏樱花。富士山上扬汉旗,樱花树下醉胡姬。") print("Python从文件中读取学生成绩，并计算最高分/最低分/平均分 \n") 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 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)) print("Python 版本", platform.python_version()) |
