如何使用python将日期转换为周级别，并使用周日作为周的开始日期？

import datetime
from dateutil.relativedelta import relativedelta

def convert_to_week(date):
    # 获取给定日期的周几
    weekday = date.weekday()
    
    # 将周几转换为以周日为开始的周几
    start_of_week = (weekday + 1) % 7
    
    # 计算给定日期所在周的开始日期
    start_date = date - datetime.timedelta(days=start_of_week)
    
    # 计算给定日期所在周的结束日期
    end_date = start_date + datetime.timedelta(days=6)
    
    # 返回结果
    return start_date, end_date

# 获取当前日期
current_date = datetime.datetime.now().date()

# 转换为周级别
start_date, end_date = convert_to_week(current_date)

# 打印结果
print("当前日期：", current_date)
print("所在周的开始日期：", start_date)
print("所在周的结束日期：", end_date)
