Basic use of time in Python

Formatted date

We can use the Strftime method of the time module to format the date:

Time.  Strftime(format[, T])      

#!/usr/bin/python#-*-Coding:utf-8-*-ImportTime# Formatted as 2016-03-20 11:45:39 formPrintTime.Strftime("%y-%m-%d%h:%m:%s",Time.LocalTime()) # formatted as Sat 28 22:24:24 2016 formPrint time.  Strftime("%a%b%d%h:%m:%s%Y", time.  LocalTime()) # Converts the format string to timestamp a = "Sat Mar 22:24:24"print time . C22>mktime(time.  Strptime(a,"%a%b%d%h:%m:%s%Y"))          

The result of the above example output:

---£ º £ThuApr:  1459175064.0              

Python format symbols in time Date:

• %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 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

Time Module

The time module contains the following built-in functions, both temporal and conversion time formats:

Serial Number	Functions and descriptions
1	Time.altzone Returns the number of seconds to offset the daylight saving time region in West Greenwich. If the region returns negative values in eastern Greenwich (such as Western Europe, including the UK). Available for daylight saving time enabled regions.
2	Time.asctime ([Tupletime]) Accepts a time tuple and returns a read-only string of 24 characters in the form "Tue Dec 11 18:07:14 2008" (December 11, 2008 Tuesday 18:07 14 seconds).
3	Time.clock () The number of seconds used to calculate the floating-point count returns the current CPU time. It is more useful than time.time () to measure the time spent on different programs.
4	Time.ctime ([secs]) function equivalent to Asctime (localtime (secs)), parameter is not given equal to Asctime ()
5	Time.gmtime ([secs]) Receives the time suffix (the number of floating-point seconds elapsed after the 1970 era) and returns the time-tuple T in Greenwich Astronomical time. Note: T.TM_ISDST is always 0
6	Time.localtime ([secs]) The Receive time suffix (the number of floating-point seconds after the 1970 era) and the time-of-day tuple T (t.tm_isdst 0 or 1, depending on whether the local time is daylight saving).
7	Time.mktime (Tupletime) Accepts the time tuple and returns the time suffix (the number of floating-point seconds elapsed after the 1970 era).
8	Time.sleep (secs) Postpone the call thread's run, secs refers to the number of seconds.
9	Time.strftime (Fmt[,tupletime]) Receives a time tuple and returns the local time as a readable string, formatted as determined by the FMT.
10	Time.strptime (str,fmt= '%a%b%d%h:%m:%s%Y ') Resolves a time string to a time tuple according to the format of the FMT.
11	Time.time () Returns the timestamp of the current time (the number of floating-point seconds elapsed after the 1970 era).
12	Time.tzset () Re-initializes time-related settings according to the environment variable TZ.

The time module contains the following 2 very important properties:

Serial Number	Properties and Descriptions
1	Time.timezone The attribute Time.timezone is the number of seconds (>0, Americas; <=0 most of Europe, Asia, and Africa) from Greenwich in the local time zone (daylight saving is not started).
2	Time.tzname The Time.tzname property contains a pair of different strings depending on the situation, which is the local time zone name with daylight savings, and No.

Calendar Module

The functions of this module are calendar-related, such as printing a month's character calendar.

Monday is the default first day of the week, and Sunday is the default last day. You need to call the Calendar.setfirstweekday () function to change the settings. The module contains the following built-in functions:

Serial Number	Functions and descriptions
1	Calendar.calendar (year,w=2,l=1,c=6) Returns the year calendar of a multi-line string format with a 3-month line with a distance of C. The daily width interval is w characters. The length of each line is 21* w+18+2* C. L is the number of rows per week.
2	Calendar.firstweekday () Returns the settings for the current weekly start date. By default, 0 is returned when the Caendar module is first loaded, which is Monday.
3	Calendar.isleap (year) is a leap year that returns true, otherwise false.
4	Calendar.leapdays (Y1,y2) Returns the total number of leap years between y1,y2 two.
5	Calendar.month (year,month,w=2,l=1) Returns a multi-line string format for year month calendar, two row headings, and one week row. The daily width interval is w characters. The length of each line is 7* w+6. L is the number of rows per week.
6	Calendar.monthcalendar (Year,month) Returns a single-level nested list of integers. Each sub-list is loaded with integers representing one weeks. The date of year month is set to 0, and the day of the month is indicated by the day of the week, starting from 1.
7	Calendar.monthrange (Year,month) Returns a two integer. The first is the day of the week of the month, and the second is the date code for that month. Day from 0 (Monday) to 6 (Sunday); The month is from 1 to 12.
8	Calendar.prcal (year,w=2,l=1,c=6) Equivalent to print Calendar.calendar (year,w,l,c).
9	Calendar.prmonth (year,month,w=2,l=1) Equivalent to print Calendar.calendar (year,w,l,c).
10	Calendar.setfirstweekday (Weekday) Set the starting date code for the week. 0 (Monday) to 6 (Sunday).
11	CALENDAR.TIMEGM (Tupletime) In contrast to Time.gmtime: accepts a time tuple form, returning the time suffix (the number of floating-point seconds elapsed after the 1970 era).
12	Calendar.weekday (Year,month,day) Returns the date code for the given date. 0 (Monday) to 6 (Sunday). The month is 1 (January) to 12 (December).
