如何计算两个日期之间的天数差？

import datetime

def get_date_difference(start_date, end_date):
    # 将日期字符串转换为datetime对象
    start_date = datetime.datetime.strptime(start_date, "%Y-%m-%d")
    end_date = datetime.datetime.strptime(end_date, "%Y-%m-%d")

    # 计算时间差
    time_difference = end_date - start_date

    # 将时间差转换为天数
    days_difference = time_difference.days

    return days_difference

# 示例用法
start_date = "2022-01-01"
end_date = "2022-01-10"
difference = get_date_difference(start_date, end_date)
print("日期差：", difference, "天")
