This article introduces the knowledge about "what is the meaning of time tuple and time date in Python". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

Time tuple (time.struct_time)

Python time tuple is a relatively important type, through the time tuple we can get, the day of the week, the day of the year and other information.

import time# localtime = time.localtime()# time.struct_time(tm_year=2019, tm_mon=11, tm_mday=3, tm_hour=9, tm_min=8, tm_sec=21, tm_wday=0, tm_yday=307, tm_isdst=0)print(type(localtime))print(localtime)for attr in localtime: print(attr) 2. Time formatting

Time formatting is a very common feature, whether it is from string to struct_time, date, datetime, or struct_time, date, datetime to string.

Format mainly involves two functions: strftime: str represents a string, f is format, time is time, that is, the format is a string strptime: str represents a string, p is parse, time is time, that is, the string is parsed into time

Both time and datetime have these two functions, which will be introduced later. Let's first look at the meaning of formatting.

Format Meaning %y Two-digit year representation, 00-99%Y Four-digit year representation, 0000-9999%m Month, 01-12%d Date, 0-31%H24 Hours, 0-23%I12 Hours, 01-12%M Minutes, 00-59%S Seconds, 00-59%a Local Simplified Name of the Week %A Local Full Name of the Week %b Local Simplified Name of the Month %B Local Full Name of the Month %c Local Date and Time Representation %j Day of Day, 001-366%p Local A.M\P.M%U Week of Day, 00 -53, Sunday is the beginning of the week %W Week of Day, 00 - 53, Monday is the beginning of the week %w Day of Day, 0-6, Sunday is the beginning of the week %x local date %X local time %Z name of current time zone %%% matches because it is treated as an escape character

III. Time

The time module mainly deals with the formatting and parsing of time tuples (struct_time).

There are also functions for localization time, get timestamp, program hibernation, etc.

Note the distinction between datetime and datetime.time. datetime.time is the time part of date and time in the general sense, mainly hours, minutes and seconds.

import time#Greenwich astronomical time tuple print (time.gmtime())print (time.gmtime(1577851199))#local time tuple print (time.localtime())print (time.localtime(1577851199))#formatted time # time.asctime ([tupletime])print (time.asctime())# time.ctime([secs])print (time.ctime())#formatted as 2020-01-01 11:59:59 form print (time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())#Convert format string to timestamp a = "2020-01-01 11:59:59"str2TT = time.strptime(a, "%Y-%m-%d %H:%M:%S")#Timetuples to timestamp ts = time.mktime(str2TT)print(ts)#Timestamp print(time.time())#Sleep seconds time.sleep(1)

datetime module mainly uses: datetime.date: date (2025-01-01) datetime.time: time (12:00:00) datetime.datetime: period (2025-01-01 12:00:00)

import datetimeimport timetoday = datetime.date.today ()print(today)print (type(today))#day of the week, isoweekday Sunday is the first day, weekday Monday is the first day print (today.isoweekday())print (today.weekday())#time tuple print (today.timetuple())#day number print (today.toordinal())datetime.date.fromordinal (today.toordinal())print(datetime.date(2020, 1, 1))datetime.date.fromtimestamp(time.time())print(datetime.time(12, 59, 59, 999))#nowlocaldateprint (datetime.datetime.now ())#nowutc dateprint (datetime.datetime.utcnow())print(datetime.datetime(2020, 1, 31, 12, 59, 59, 0))#string to date print(datetime.datetime.strptime ('2020 -1-1 12: 01','%Y-%m-%d %H:% M'))#date formatting print(datetime.datetime.now ().strftime ('% Y-%m-%d %H:% M'))

The most commonly used are:

#String get date datetime.datetime.strptime ('2020 -1-1 12: 01','%Y-%m-%d %H:% M')#Date format datetime.datetime.now().strftime ('% Y-%m-%d %H:%M:% S')

Timedelta is also under the datetime module, mainly used for date calculation.

This is useful when you need to use a time interval, such as the previous month, day, week, etc., which can be easily obtained using datetime and timedelta.

import datetimeimport timetoday = datetime.date.today ()#Last day of last month lastMonthLastDay = datetime.date(today.year, today.month, 1) -datedelta (1)print(lastMonthDay)#First day of last month lastMonthFirstDay = datetime.date (lastMonthLastDay.year, lastMonthLastDay.month, LastMonthDay 1)print(lastMonthFirstDay)#a week ago print(today - datetime.timedelta(7))#thisMonday = today - datetime.timedelta(today.isoweekday()-1)print(thisMonday)#thisSunday = thisMonday - datetime.timedelta(7)print(lastMonday)#lastSunday = today -datetime.timedelta(days=today.isoweekday())print(lastSunday)#Last Monday lastMonday = lastSunday - datetime.timedelta(days=6)print(lastMonday)# 8 hours later print(datetime.datetime.now () + datetime.timedelta(hours=8))start = datetime.datetime.now ()time.sleep(1)end = datetime.datetime.now()diff = end - start# print(type(diff))print(diff) VI. calendarimport calendar#whether it is a leap year print(calendar.isleap(2020))

calendar is calendar
