如何获取数组中每个月的最新时间戳

timestamps = [1622505600, 1625097600, 1627776000, 1630454400, 1633046400, 1635724800]

latest_timestamps = {}

for timestamp in timestamps:
    year_month = (timestamp // (30 * 24 * 60 * 60), timestamp // (24 * 60 * 60) % 30)
    if year_month in latest_timestamps:
        latest_timestamps[year_month] = max(latest_timestamps[year_month], timestamp)
    else:
        latest_timestamps[year_month] = timestamp

for year_month, latest_timestamp in latest_timestamps.items():
    year, month = year_month
    print(f"最新时间戳：{latest_timestamp}，对应的年份和月份：{year}-{month}")
