Getting current date by Python datetime now() function

In this tutorial, you are going to learn how to get the current date and time by now() function of Python datetime() module.

Later, you can also see the other ways of getting the current time.

How to use now() function?

The timedate now() function returns the current local date and time.

The general syntax for using the now() function is:

datetime.now(tz=None)

Where tz argument specifies the time zone. If a value of None is given, this is like today(). For other than None value, it must be an instance of the tzinfo subclass. You may learn more about tzinfo subclass here.

An example of Python now() to get current local date and time

Similarly, you may get the GMT time by using gmttime() function in the strftime() function as follows:


The output should be GMT time like this:

2018-12-04 09:41:09

You can see, this time we got the time as well as date. You may use the formatting directives as per the requirements.
