比较QDateTime

Question

self.start_date = ui.new_scheduled_transmition_day_start_date_2.date().toString()
self.time_start = ui.new_scheduled_transmition_day_start_time_2.time().toString()
self.end_date = ui.new_scheduled_transmition_day_end_date_2.date().toString()
self.end_time = ui.new_scheduled_transmition_day_end_time_2.time().toString()

我想看看start_datetime

任何建议都是有用的。

我试过这个：

date_1 = self.start_date+" "+self.time_start
date_2 = self.end_date+" "+self.end_time
date_1_time_obj = datetime.datetime.strptime(date_1, '%a %b %d %Y %H:%M:%S')
date_2_time_obj = datetime.datetime.strptime(date_2, '%a %b %d %Y %H:%M:%S')
print(date_1_time_obj<date_2_time_obj)

错误：

ValueError: time data '╙άέ ╔άΊ 1 2000 00:00:00' does not match format '%a %b %d %Y %H:%M:%S'

发生此错误是因为.toString()以本地格式返回一周和一个月的日期(希腊字符)。

self.start_date = ui.new_scheduled_transmition_day_start_date_2.date().toPyDate()
self.time_start = ui.new_scheduled_transmition_day_start_time_2.time().toPyTime()
self.end_date = ui.new_scheduled_transmition_day_end_date_2.date().toPyDate()
self.end_time = ui.new_scheduled_transmition_day_end_time_2.time().toPyTime()
                
                
                
date_1_time_obj = datetime.datetime.combine(self.start_date, self.time_start)
date_2_time_obj = datetime.datetime.combine(self.end_date, self.end_time)
print(date_1_time_obj<date_2_time_obj)

如果您想按标题所说的那样做:比较QDateTime类型的对象，这已经是可能的了。

date1 = QDateTime.currentDateTime()
date2 = QDateTime.currentDateTime().addMonths(1)

date1 < date2
=> True

如果你想先把日期和时间结合起来，它应该这样做：

start_date = ui.new_scheduled_transmition_day_start_date_2
start_time = ui.new_scheduled_transmition_day_start_time_2

end_date = ui.new_scheduled_transmition_day_end_date_2
end_time = ui.new_scheduled_transmition_day_end_time_2

date_1 = QDateTime(start_date).addMSecs(start_time.msecsSinceStartOfDay())
date_2 = QDateTime(end_date).addMSecs(end_time.msecsSinceStartOfDay())

date1 < date2
