%S: second as a zero-padded decimal number.

%M: minute as a zero-padded decimal number.

%H: hour (24-hour clock) as a zero-padded decimal number.

%d: day of the month as a zero-padded decimal number.

%m: month as a zero-padded decimal number.

%Y: year with century as a decimal number.

The format codes used in this example are:

The strftime() method returns a string representing the date, controlled by an explicit format string. The fourth line print (now.strftime("%Y-%m-%d %H:%M:%S")) uses the strftime() method of the datetime object to format the date and time as a string in the format "YYYY-MM-DD HH:MM:SS" and prints it to the console.The third line print ("Current date and time : ") prints the string "Current date and time : " to the console.The second line now = () creates a datetime object for the current date and time.The first line import datetime imports the datetime module which supplies classes for manipulating dates and times.The said code imports the "datetime" module, gets the current date and time, and finally prints it in a formatted string. Format codes referring to hours, minutes or seconds will see 0 values. If optional argument tz is None or not specified, this is like today().ĭate.strftime(format) returns a string representing the date, controlled by an explicit format string. datetime.now(tz=None) returns the current local date and time. The datetime module supplies classes for manipulating dates and times in both simple and complex ways. Let's say that the 2 nd () call happens one microsecond later (I am reproducing the behavior using the delta object, as the times involved here are waaay too small for me to be able to to run the line at the exact time when this behavior is encountered).Write a Python program to display the current date and time.Let now0 to be the result of the 1 st call made to ().> delta = datetime.timedelta(microseconds=1) But, when the 1 st call is at the very end of a (microsecond?) period, and the 2 nd one is at the beginning of the next one, you'd get this behavior:ĭatetime.datetime(2018, 2, 20, 12, 23, 23, 1000).Since the CPU speeds are very high nowadays, every such call takes a very small amount of time (much less than microseconds, I presume) You have 2 such calls (even if they are on the same line).

Every () produces a datetime.datetime object ( : ), which is the current date & time at the moment the call was made.You are encountering a "corner case" situation.
