使用时区获取周范围

import datetime
import pytz

def get_week_range(date_str, timezone):
    # 将日期字符串转换为日期对象
    date = datetime.datetime.strptime(date_str, "%Y-%m-%d").date()

    # 设置时区
    tz = pytz.timezone(timezone)

    # 将日期对象转换为指定时区的日期时间对象
    date_time = tz.localize(datetime.datetime.combine(date, datetime.datetime.min.time()))

    # 获取给定日期所在周的起始日期和结束日期
    start_date = date_time - datetime.timedelta(days=date_time.weekday())
    end_date = start_date + datetime.timedelta(days=6)

    # 格式化起始日期和结束日期为指定的日期字符串
    start_date_str = start_date.strftime("%Y-%m-%d")
    end_date_str = end_date.strftime("%Y-%m-%d")

    return start_date_str, end_date_str

# 示例用法
date_str = "2022-01-01"
timezone = "Asia/Shanghai"
start_date, end_date = get_week_range(date_str, timezone)
print("起始日期:", start_date)
print("结束日期:", end_date)
