如何从日期范围中获取平均值？

import datetime

def get_average_from_date_range(start_date, end_date):
    start_timestamp = datetime.datetime.strptime(start_date, "%Y-%m-%d").timestamp()
    end_timestamp = datetime.datetime.strptime(end_date, "%Y-%m-%d").timestamp()

    total = 0
    days = 0

    current_timestamp = start_timestamp
    while current_timestamp <= end_timestamp:
        total += current_timestamp
        days += 1
        current_timestamp += 86400  # 一天的秒数

    average_timestamp = total / days
    return datetime.datetime.fromtimestamp(average_timestamp).strftime("%Y-%m-%d")

start_date = "2022-01-01"
end_date = "2022-01-10"
average_date = get_average_from_date_range(start_date, end_date)
print("平均日期:", average_date)
