Skipping code for error cases, the default fromutc() implementation acts For a time t, str(t) is equivalent to t.isoformat(). Method 1: By using date (): date () method of datetime module returns only the date component of datetime, excluding time part. For time objects, the format codes for year, month, and day should not For date objects, the format codes for hours, minutes, seconds, and can be set to an instance of a subclass of the abstract tzinfo class.
