  Time Functions in Python | Set to 1 (time (), time (), sleep () & # 8230;)

File handling | Python Methods and Functions

Operations by time:

1. time () : — this function is used to count the number of seconds since the beginning of an epoch .

2. gmtime (sec) : — this function returns a structure with 9 values, each of which is a temporary attribute in a sequence. It converts seconds to time attributes (days, years, months, etc.) Until the specified seconds from the beginning of the epoch. If no seconds are specified, the time is calculated up to the present time. The structure attribute table is shown below.

Index Attributes Values ​​0 tm_year 2008 1 tm_mon 1 to 12 2 tm_mday 1 to 31 3 tm_hour 0 to 23 4 tm_min 0 to 59 5 tm_sec 0 to 61 (60 or 61 are leap -seconds) 6 tm_wday 0 to 6 7 tm_yday 1 to 366 8 tm_isdst -1, 0, 1 where -1 means Library determines DST

 # Python code to demonstrate how it works # time () and gmtime ()    # importing a time module for time operations import time    # using time () to display time since epoch print ( "Seconds elapsed since the epoch are: " , end = " ") print (time.time ())     # using gmtime () to return an attribute structure time print ( "Time calculated acc ... to given seconds is: " ) print (time.gmtime ())

Output:

Seconds elapsed since the epoch are: 1470121951.9536893 Time calculated acc. to given seconds is: time.struct_time (tm_year = 2016, tm_mon = 8, tm_mday = 2, tm_hour = 7, tm_min = 12, tm_sec = 31, tm_wday = 1, tm_yday = 215, tm_isdst = 0)

3.asctime : — this function takes a string with a time attribute, generated by gmtime (), and returns a string of 24 characters for the time .

4.ctime (sec) : — this function returns a 24-character temporary string, but takes seconds as an argument and calculates the time until the specified seconds . If no argument is passed, time is calculated to date.

 # Python code to demonstrate how it works # asctime () and ctime ()   # import a time module for time operations import time   # time initialization with gmtime () ti = time.gmtime ()   # using asctime () to display the time acc. by the mentioned time print ( "Time calculated using asctime () is: " , end = " ") print (time.asctime (ti))     # using ctime ( ) to display the time string using seconds print ( " Time calculated using ctime () is: " , end = " ") print (time.ctime ())

Output:

Time calculated using asctime () is: Tue Aug 2 07:47:02 2016 Time calculated using ctime () is: Tue Aug 2 07:47:02 2016

5. sleep (sec) : — This method is used to track program execution over the time specified in the arguments.

 # Python code to demonstrate how it works # sleep ()   # import a time module for time operations import time   # using ctime () to display the current time print ( "Start Execution:" , end = "") print (time.ctime ())    # using sleep () to call execution time.sleep ( 4 )   # using ctime () to display the current time print ( "Stop Execution:" , end = "") print ( time.ctime ())

Output:

Start Execution: Tue Aug 2 07:59:03 2016 Stop Execution: Tue Aug 2 07:59:07 2016
