将实际日期添加到csv输出文件名

import csv
from datetime import datetime

# 原始文件名
filename = "data.csv"

# 获取当前日期
current_date = datetime.now()

# 格式化日期为指定格式
formatted_date = current_date.strftime("%Y-%m-%d")

# 构建新的文件名
new_filename = f"{formatted_date}_{filename}"

# 输出文件
with open(new_filename, "w", newline="") as file:
    writer = csv.writer(file)
    writer.writerow(["Column 1", "Column 2", "Column 3"])  # 示例数据
    writer.writerow(["Data 1", "Data 2", "Data 3"])  # 示例数据
