使用Python将输出打印到CSV文件并对其进行格式化

import csv
from datetime import datetime

students = [
    {"姓名": "张三", "年龄": 20, "成绩": 90},
    {"姓名": "李四", "年龄": 22, "成绩": 85},
    {"姓名": "王五", "年龄": 21, "成绩": 95}
]

filename = datetime.now().strftime("%Y-%m-%d_%H-%M-%S") + ".csv"

with open(filename, mode='w', newline='') as file:
    writer = csv.writer(file)
    
    # 写入表头
    writer.writerow(["姓名", "年龄", "成绩"])
    
    # 写入数据
    for student in students:
        writer.writerow([student["姓名"], student["年龄"], student["成绩"]])

姓名,年龄,成绩
张三,20,90
李四,22,85
王五,21,95
