在python中获取整个日期帧的周起始日期。

import datetime
import calendar

def get_week_start_end_dates(date):
    # 获取给定日期所在周的起始日期
    start_date = date - datetime.timedelta(days=date.weekday())
    
    # 获取给定日期所在周的结束日期
    end_date = start_date + datetime.timedelta(days=6)
    
    return start_date, end_date

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

# 获取整个日期帧的周起始日期
start_date, end_date = get_week_start_end_dates(current_date)

# 打印结果
print("整个日期帧的周起始日期：", start_date)
print("整个日期帧的周结束日期：", end_date)
