The method strftime() converts a tuple or struct_time representing a time as returned by gmtime() or localtime() to a string as specified by the format argument.
If t is not provided, the current time as returned by localtime() is used. format must be a string. An exception ValueError is raised if any field in t is outside of the allowed range.
Following is the syntax for strftime() method −
t − This is the time in number of seconds to be formatted.
format − This is the directive which would be used to format given time.
The following directives can be embedded in the format string −
%a − abbreviated weekday name
%A − full weekday name
%b − abbreviated month name
%B − full month name
%c − preferred date and time representation
%C − century number (the year divided by 100, range 00 to 99)
%d − day of the month (01 to 31)
%D − same as %m/%d/%y
%e − day of the month (1 to 31)
%g − like %G, but without the century
%G − 4-digit year corresponding to the ISO week number (see %V).
%h − same as %b
%H − hour, using a 24-hour clock (00 to 23)
%I − hour, using a 12-hour clock (01 to 12)
%j − day of the year (001 to 366)
%m − month (01 to 12)
%M − minute
%n − newline character
%p − either am or pm according to the given time value
%r − time in a.m. and p.m. notation
%R − time in 24 hour notation
%S − second
%t − tab character
%T − current time, equal to %H:%M:%S
%u − weekday as a number (1 to 7), Monday=1. Warning: In Sun Solaris Sunday = 1
%U − week number of the current year, starting with the first Sunday as the first day of the first week
%V − The ISO 8601 week number of the current year (01 to 53), where week 1 is the first week that has at least 4 days in the current year, and with Monday as the first day of the week
%W − week number of the current year, starting with the first Monday as the first day of the first week
%w − day of the week as a decimal, Sunday = 0
%x − preferred date representation without the time
%X − preferred time representation without the date
%y − year without a century (range 00 to 99)
%Y − year including the century
%Z or %z − time zone or name or abbreviation
%% − a literal % character
This method does not return any value.
The following example shows the usage of strftime() method.
#!/usr/bin/python3 import time t = (2015, 12, 31, 10, 39, 45, 1, 48, 0) t = time.mktime(t) print (time.strftime("%b %d %Y %H:%M:%S", time.localtime(t)))
When we run the above program, it produces the following result −
