如何获取每年日期之间的最小值、最大值和长度？

import datetime

def get_date_range(start_date, end_date):
    start_date = datetime.datetime.strptime(start_date, "%Y-%m-%d")
    end_date = datetime.datetime.strptime(end_date, "%Y-%m-%d")

    min_date = min(start_date, end_date)
    max_date = max(start_date, end_date)
    length = (max_date - min_date).days + 1

    return min_date, max_date, length

start_date = "2022-01-01"
end_date = "2022-12-31"
min_date, max_date, length = get_date_range(start_date, end_date)

print("最小日期:", min_date.strftime("%Y-%m-%d"))
print("最大日期:", max_date.strftime("%Y-%m-%d"))
print("日期范围长度:", length)
