python网页自动化脚本 python脚本的自动化
嗨，stackoverflow社区，我想知道如何自动生成我的EPEX masterscript.py。我读到，我必须将扩展名py更改为pyw（在windows10系统上）。然后我想告诉我的脚本python网页自动化脚本，它应该在函数"datetime.date"的帮助下获取实际日期，给我属性：年、月和日。之后，它应该接管日、年、月python网页自动化脚本辅助论坛，而不是手动更改日、年和月。这个脚本现在是这样的，它将来自internetpage (beautifulsoup)的一些数据保存在PostgreSQL数据库中，但它是在手动执行下面的代码之后完成的。其主要思想是，在后台运行EPEX masterscript.py（计算机应该自动执行），并且该脚本每天在10a.m和下午6点删除两次。
你能帮我一些想法或解决方案吗？？？
这是我的代码（EPEX masterscript.py)）：
