Python library defines a function that can be primarily used to get current time and date. now() function Return the current local date and time, which is defined under datetime
module.
Syntax : datetime.now(tz)
Parameters :
tz : Specified time zone of which current time and date is required. (Uses Greenwich Meridian time by default.)
Returns : Returns the current date and time in time format.
Code #1 :
import datetime
current_time = datetime.datetime.now()
print ( "Time now at greenwich meridian is : "
, end = "")
print (current_time)
|
Output :
Time now at greenwich meridian is : 2018-03-29 10:26:23.473031
Attributes of now() :
now() has different attributes, same as attributes of time such as year, month, date, hour, minute, second.
Code #2 : Demonstrate attributes of now().
import datetime
current_time = datetime.datetime.now()
print ( "The attributes of now() are : " )
print ( "Year : " , end = "")
print (current_time.year)
print ( "Month : " , end = "")
print (current_time.month)
print ( "Day : " , end = "")
print (current_time.day)
print ( "Hour : " , end = "")
print (current_time.hour)
print ( "Minute : " , end = "")
print (current_time.minute)
print ( "Second : " , end = "")
print (current_time.second)
print ( "Microsecond : " , end = "")
print (current_time.microsecond)
|
The attributes of now() are :
Year : 2018
Month : 3
Day : 26
Hour : 20
Minute : 9
Second : 4
Microsecond : 499806
Getting time of particular timezone :
Sometimes, the need is just to get the current time of a particular timezone. now() takes timezone as input to give timezone oriented output time. But these time zones are defined in pytz library.
Code #3 : Use of now() to handle specific timezone.
import datetime
import pytz
current_time = datetime.datetime.now(pytz.timezone( 'Asia / Calcutta' ))
print ( "The current time in india is : " )
print (current_time)
|
Output:
The current time in india is :
2018-03-29 03:09:33.878000+05:30
Note : Above code won’t work on online IDE due to absence of pytz module.
Application :
While developing any real world application, we might need to show real time of any timezone. now() function can do the work here very efficiently and easily.
