将UNIX时间戳日期转换为该周的星期一

import datetime

def convert_unix_timestamp_to_monday(unix_timestamp):
    # 将UNIX时间戳转换为日期格式
    date = datetime.datetime.fromtimestamp(unix_timestamp)

    # 获取该日期对应的星期几（星期一为0，星期日为6）
    weekday = date.weekday()

    # 计算日期差
    days_diff = (weekday + 6) % 7

    # 计算该周的星期一的日期
    monday = date - datetime.timedelta(days=days_diff)

    return monday

# 示例使用
unix_timestamp = 1635724800  # 假设给定的UNIX时间戳
monday = convert_unix_timestamp_to_monday(unix_timestamp)
print(monday.strftime('%Y-%m-%d'))  # 输出格式化的日期字符串，如2021-11-01
