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 :
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().
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.
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.
