Telethon 上周仅从电报组中抓取

如何解决Telethon 上周仅从电报组中抓取

我有一个用于抓取的电视广播脚本。 我对这个脚本有几个问题：

1. 此脚本抓取本月在线的用户。 应该怎么做才能使它只在最后 7 天刮擦？还是更多……？

2. 此脚本将用户写入 csv 文件。 如何使其写入 xlsx 文件？

3. 当脚本完成它的工作时，它会以以下格式写入“last seen”： "UserStatusOffline(was_online=datetime.datetime(2021,4,16,10,52,53,tzinfo=datetime.timezone.utc))" 如何使它以这种格式写入： was_online = (年、月、日)？

或者不同的东西... 保持简短很重要。

谢谢大家，祝你有美好的一天！ 这是脚本：
