Question

我需要计算假期的日期而不是学期的日期，但是日历文件（ics）就是这样！

我需要这样的结果：第一学期开始日期= 2019-04-05 结束日期= 2019-04-23

因此，第1学期的结束是假期的开始，而第2学期的开始就是假期的结束。这也给第四学期带来了一个问题，第四学期的假期是下一年第一学期的开始。

这是日历文件的示例

from icalendar import Calendar, Event
g = open(VSH,'rb')
mycal = Calendar.from_ical(g.read())
for component in mycal.walk():
    if component.name == "VEVENT":
        mySummary = component.get('summary')

        if component.get('summary').find("starts") > 1:
            print(component.get('summary').replace("starts",""))
            print("we have a start event", component.get('dtstart').dt)
        elif component.get('summary').find("ends") > 1:
            print("we have a end event", component.get('dtend').dt)
g.close()

以下代码中计算日期的最佳方法是什么？
