从字典的键中选择两点之间的所有datetime对象

import datetime

def select_datetime_between_points(dictionary, start_key, end_key):
    keys = list(dictionary.keys())
    keys.sort()

    start_index = keys.index(start_key)
    end_index = keys.index(end_key)

    selected_datetimes = []
    for i in range(start_index, end_index + 1):
        datetime_obj = datetime.datetime.strptime(keys[i], "%Y-%m-%d %H:%M:%S")
        selected_datetimes.append(datetime_obj)

    return selected_datetimes
