Python time processing method

In practice, if you encounter a time processing problem, you need to compare Sep06, 201419: 30 (UTC time) with the current time sooner or later. we know this 2014-09-0619: in practice, if a time processing problem occurs for a 30-Period, you need to compare the Sep 06,201 4 (UTC time) with the current time to know the operation of the time in the format. Therefore, when processing, you just want

First, the sep format time is converted into the time format in the following format, and no related function is found. Therefore, I wrote a program and only recorded it for query.

The code is as follows:

#-*-Coding: UTF-8-*-from datetime import datefrom datetime import datetimefrom datetime import timedelta ### if the current time is returned, you can simply write it as # time. localtime () ### the returned UTC time ## time. gmtime () # lt = time. localtime () # tm = time. gmtime () # ft = time. strftime ('% Y-% m-% d % H-% M', lt) # ft2 = time. strftime ('% Y-% m-% d % H: % M', tm) # print ft, ft2 # print' -------------------------------------------------------- '# now = datetime. datetime. now () # now = now. replace (day = 1) # print now. time () # mytime = ['2017-09-06 20:19 '] # mytime2 = '2017-10-09' # str = "". join (mytime) # print str # retime = datetime. strptime (str, '% Y-% m-% d % H: % M') # print retime # retime = retime + timedelta (hours = 8) # print retime # tdtime = datetime. now () # print tdtime # if retime <= tdtime-timedelta (days = 7): # print "too early" ### Sep 06,201 4 monthdic = {'Jan ': '01', 'Feb': '02', 'Mar ': '03', 'Apr': '04', 'may': '05 ', 'Jun ': '06 ', 'Jul': '07', 'Aug': '08 ', 'Sep': '09', 'Oct': '10', 'Nov ': '11', 'Dec ': '12'} def time_format (timestr): timestr = timestr. replace (',', '') # print timestr timelist = timestr. split () # print timelist mon = "". join (timelist [0]) # print mon timelist [0] = monthdic [mon] # print timelist mytime = "". join (timelist [2]) + '-' + "". join (timelist [0]) + '-' + "". join (timelist [1]) + ''+ "". join (timelist [3]) return mytimeif name = 'main': timestr = 'sep 06,201 4 'str = time_format (timestr) print str mytime = datetime. strptime (str, '% Y-% m-% d % H: % M') print mytime = mytime + timedelta (hours = 8) print mytime tdtime = datetime. now () print tdtime if mytime <= tdtime-timedelta (days = 7): print "too early"

The above is the details of the time processing method using python. For more information, see other related articles in the first PHP community!
