Python Timing Module Time & datetime & Calendar Introduction

There are two modules for Python processing time, which are times, datetime, calendar

1> time

Print(Time.gmtime ())Print(Time.localtime ())#the current time is returned by a Time.struct_time objectPrint(Time.time ())#The time stamp of the current time is returnedLocalTime =time.localtime ()Print("tm_gmtoff={}". Format (localtime.tm_gmtoff))Print("tm_hour={}". Format (Localtime.tm_hour))#whenPrint("tm_isdst={}". Format (LOCALTIME.TM_ISDST))#whether daylight saving timePrint("tm_mday={}". Format (Localtime.tm_mday))#RIPrint("tm_min={}". Format (localtime.tm_min))#pointsPrint("tm_mon={}". Format (Localtime.tm_mon))#MonthPrint("tm_sec={}". Format (LOCALTIME.TM_SEC))#secondsPrint("tm_wday={}". Format (Localtime.tm_wday))#weeksPrint("tm_yday={}". Format (Localtime.tm_yday))#the day ordinal of a yearPrint("tm_year={}". Format (localtime.tm_year))#yearsPrint("tm_zone={}". Format (localtime.tm_zone)) TS= Time.mktime (localtime)#get time stamps at a given timePrint(TS)#Format output TimePrint(Time.strftime ("%y/%m/%d", localtime))#the time string is returnedTimestr="2017-08-05 23:00:00"Print(Time.strptime (TIMESTR,"%y-%m-%d%x"))#a Time.struct_time object is returned.

2> datetime

#in the DateTime module, there are several sub-modules, respectively:#Date: Processing date#time: Minutes and minutes of processing, subtle#datetime: Processing date, hour, minute, subtle#see the properties and methods of each module separatelyPrint('----------------The date module--------------------')Print(dir (datetime.date))Print('----------------Time Module--------------------')Print(dir (datetime.time))Print('----------------a datetime module----------------')Print(dir (datetime.datetime))#here is the main look at the datetime module fromDatetimeImportdatetimePrint(DateTime. Minyear,datetime. Maxyear)#maximum year and minimum year, you can make your own default said 9999, 1Datetime. Maxyear = 100000Print(DateTime. Maxyear)#to view the types that datetime belongs toPrint(Type (datetime))#discovery is a type#Here's a record of the relationship between type and Object#Object is the top of all parent-child relationships (inheritance relationships), all of which are the parent of the data type, and type is all type instance relationships#At the top, all objects are instances of it#As you can understand, object is a type that is an instance of the type Object#The above understanding is only a personal understanding, if there is a wrong place, please correct#Get current TimeCurrentTime = DateTime.Now ()#a Datetime.datetime object is returned.Print(currenttime)Print(Currenttime.strftime ('%x%x'))#format the current time of the output#gets the timestamp of the current timePrint(Currenttime.timestamp ()) d=datetime (2017,8,6,11,52,30)#custom format output for a specified time#%y Two-digit year representation (00-99)#%Y Four-digit year representation (000-9999)#%m Month (01-12)#One day in%d months (0-31)#%H 24-hour system hours (0-23)#%I 12-hour hours (01-12)#%M minutes (00=59)#%s seconds (00-59)#%a Local Simplified week name#%A Local Full week name#%b a locally simplified month name#%B Local Full month name#%c Local corresponding date representation and time representation#%j Day of the Year (001-366)#%p the equivalent of a local a.m. or P.M.#%u weeks of the year (00-53) Sunday is the beginning of the week#%w Week (0-6), Sunday for the beginning of the week#%W Week of the Year (00-53) Monday is the beginning of the week#%x Local corresponding date representation#%x Local corresponding time representation#%Z The name of the current time zone#percent% of the number itself     Print(D.strftime ("%y-%m-%d%p"))#2017-08-06 AM A string#Show English formatPrint(D.ctime ())#Sun 6 11:52:30#Show Calendar (year, Week of the year, weeks)Print(D.isocalendar ())#(2017, 31, 7) returns a tuple that needs to be directed to a value when usedPrint(Datetime.today ())

3> Calendar

#get a calendar for a yearPrint(Calendar.calendar (2017))#get a calendar for a monthPrint(Calendar.month (2017, 8))#determine whether a year is a leap yearsPrint(Calendar.isleap (2017))#detects the number of leap years between two year (S )Print(Calendar.leapdays (1990,2017))#Convert calendar to HTML format, you can set date, week, etc.Cal =Calendar. Htmlcalendar (Calendar. MONDAY)Print(CAL)Print(Cal.formatyear (2017))
