如何用范围内的时间填充缺失的日期？

import datetime

def fill_missing_dates(start_date, end_date, missing_dates):
    date_range = [start_date + datetime.timedelta(days=x) for x in range((end_date - start_date).days + 1)]
    filled_dates = []

    for date in date_range:
        if date in missing_dates:
            # 根据需求选择不同的填充方式，这里使用前一天的日期进行填充
            filled_dates.append(date - datetime.timedelta(days=1))
        else:
            filled_dates.append(date)

    return filled_dates

# 示例数据
start_date = datetime.date(2022, 1, 1)
end_date = datetime.date(2022, 1, 10)
missing_dates = [datetime.date(2022, 1, 3), datetime.date(2022, 1, 6)]

filled_dates = fill_missing_dates(start_date, end_date, missing_dates)
print(filled_dates)

[datetime.date(2022, 1, 1), datetime.date(2022, 1, 2), datetime.date(2022, 1, 2), datetime.date(2022, 1, 4), datetime.date(2022, 1, 5), datetime.date(2022, 1, 5), datetime.date(2022, 1, 7), datetime.date(2022, 1, 8), datetime.date(2022, 1, 9), datetime.date(2022, 1, 10)]
