根据开始日期和结束日期生成分组时间序列

import datetime

def generate_time_series(start_date, end_date):
    time_series = {}
    current_date = start_date

    while current_date <= end_date:
        # 根据具体需求进行相应的操作，这里仅示例将时间点按照日期进行分组
        date_str = current_date.strftime("%Y-%m-%d")
        time_series.setdefault(date_str, [])
        time_series[date_str].append(current_date)

        # 生成下一个时间点
        current_date += datetime.timedelta(days=1)

    return time_series

# 示例用法
start_date = datetime.date(2022, 1, 1)
end_date = datetime.date(2022, 1, 5)
time_series = generate_time_series(start_date, end_date)

# 打印生成的分组时间序列
for date_str, dates in time_series.items():
    print(date_str, dates)
