考虑到日期和时间值，如何在Python中从csv创建字典？

import csv
from datetime import datetime

with open('data.csv', 'r') as csvfile:
    reader = csv.reader(csvfile)
    next(reader)  # 跳过标题行
    
    data_dict = {}
    for row in reader:
        date_str = row[0]  # 日期值所在的列
        time_str = row[1]  # 时间值所在的列
        
        # 将日期字符串转换为日期对象
        date_obj = datetime.strptime(date_str, '%Y-%m-%d').date()
        
        # 将时间字符串转换为时间对象
        time_obj = datetime.strptime(time_str, '%H:%M:%S').time()
        
        # 创建日期和时间的字典键值对
        data_dict[date_obj] = time_obj

date_to_lookup = datetime.strptime('2022-01-01', '%Y-%m-%d').date()
time_value = data_dict[date_to_lookup]
