如何在Python中以升序从csv文件中提取日期

import csv
from datetime import datetime

with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    next(reader)  # 跳过标题行
    dates = []
    for row in reader:
        date_str = row[0]  # 假设日期在第一列
        date = datetime.strptime(date_str, '%Y-%m-%d')  # 将日期字符串转换为datetime对象
        dates.append(date)

sorted_dates = sorted(dates)

for date in sorted_dates:
    print(date.strftime('%Y-%m-%d'))  # 将datetime对象转换为字符串并打印
