The comparison method of DateTime in Python uses

The datetime module in Python is a powerful, but complex, module that deals with time-related content. The code is used to find the timestamp from MySQL and the current time comparison, the method of finding the difference Import datetime Lasttime=a.get_last_timestamp (sid=40) [ -1]["Last_time"] #取到timestamp Delta = datetime.datetime.now ()-lasttime #使用datetime. DateTime.Now () Gets the current time and then asks for a difference If Delta > Datetime.timedelta (minutes=8): #如果时间差大于 8 minutes, (if 8 hours is hours=8, if 8 seconds is seconds=8) ..... #datetime. Timedelta () This method is quite special, and the explanation for this class in python.org is: Class DateTime. Timedelta ([days [, seconds [, microseconds [, milliseconds [, minutes [, hours [, weeks]]] Parameters can be used together, such as Datetime.timedelta (HOURS=5,MINUTES=8,SECONDS=10), representing 5 hours 8 minutes 10 seconds
