获取一个月内特定一周的日期范围

import datetime

def get_week_date_range(start_date):
    # 计算起始日期所在周的第一天和最后一天
    start_of_week = start_date - datetime.timedelta(days=start_date.weekday())
    end_of_week = start_of_week + datetime.timedelta(days=6)

    # 计算一个月内的起始日期和结束日期
    start_of_month = start_date.replace(day=1)
    end_of_month = (start_of_month + datetime.timedelta(days=32)).replace(day=1) - datetime.timedelta(days=1)

    # 确保起始日期和结束日期在一个月内
    start_date = max(start_of_week, start_of_month)
    end_date = min(end_of_week, end_of_month)

    return start_date, end_date

# 示例使用：获取当前日期所在月份的第二周日期范围
current_date = datetime.datetime.now()
start_date, end_date = get_week_date_range(current_date)

print("起始日期:", start_date.strftime("%Y-%m-%d"))
print("结束日期:", end_date.strftime("%Y-%m-%d"))
