获取两个日期之间的时间适用于天和小时，但不适用于分钟或秒

import datetime

def get_time_difference(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()
    time_difference = int(end_timestamp - start_timestamp)
    days = time_difference // 86400
    hours = (time_difference % 86400) // 3600
    return days, hours

start_date = "2022-01-01"
end_date = "2022-01-03"
days, hours = get_time_difference(start_date, end_date)
print("时间差为{}天{}小时".format(days, hours))
