将包含数字数组的嵌套字典保存到CSV文件中

import csv

data = [
    {"name": "John", "age": 25, "scores": [90, 85, 92]},
    {"name": "Alice", "age": 30, "scores": [80, 75, 88]},
    {"name": "Bob", "age": 28, "scores": [95, 89, 87]}
]

fields = ["name", "age", "scores"]

filename = "data.csv"

with open(filename, 'w', newline='') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=fields)
    writer.writeheader()  # 写入列名
    writer.writerows(data)  # 写入数据

with open(filename, 'r') as csvfile:
    reader = csv.DictReader(csvfile)
    for row in reader:
        print(row)
