import datetime

def get_week_dates(year, month, week):
    # 获取指定年份和周数的开始日期和结束日期
    start_date = datetime.datetime.strptime(f'{year}-{month}-1', '%Y-%m-%w').date()
    start_date += datetime.timedelta(days=(week-1)*7)
    end_date = start_date + datetime.timedelta(days=6)
    return start_date, end_date

# 用户输入年份、月份和周数
year = int(input("请输入年份："))
month = int(input("请输入月份："))
week = int(input("请输入周数："))

start_date, end_date = get_week_dates(year, month, week)
print(f"第{week}周的开始日期是：{start_date}")
