如何拆分抓取的数据并将其保存在具有完整链接和描述的csv的单独列中？

import csv

# 假设抓取的数据保存在一个列表中，每个数据项为字典
data = [
    {"title": "文章1", "link": "https://example.com/article1", "description": "这是文章1的描述"},
    {"title": "文章2", "link": "https://example.com/article2", "description": "这是文章2的描述"},
    {"title": "文章3", "link": "https://example.com/article3", "description": "这是文章3的描述"}
]

# 定义CSV文件路径和列标题
csv_file = "data.csv"
csv_columns = ["链接", "描述"]

# 写入数据到CSV文件
with open(csv_file, "w", newline="", encoding="utf-8") as file:
    writer = csv.DictWriter(file, fieldnames=csv_columns)
    writer.writeheader()  # 写入列标题
    for item in data:
        writer.writerow({"链接": item["link"], "描述": item["description"]})

print("数据已保存到CSV文件中。")
