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

# 导入系统包
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")

# 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))

print("Python 版本", platform.python_version())
