Datetime Attributes

Like for date objects, there are also attributes for datetime allowing us to extract any part of the date and time we want. These are:

  • datetime.year - extracts year;
  • datetime.month - extracts month;
  • datetime.day - extracts day of the month;
  • datetime.hour - extracts hour from time;
  • datetime.minute - extracts minute from time;
  • datetime.second - extracts second from time;
  • datetime.microsecond - extracts microseconds from time.

For example, from the datetime object, we can extract only day, minute, and second.


              
123456789

            
# Load class from library
from datetime import datetime

# Create datetime object
dt = datetime(2020, 11, 1, 11, 20, 25)

# Extract day, minute and second
print("Day of month:", dt.day)
print(f"Minute:Second - {dt.minute}:{dt.second}")
copy

Task

Given datetime object dt with the assigned date "May 15, 2013, 18:10:52". Replace the first two ___ parts with the day and month of dt (like 15.5), and the last two ones with the hour and minute (like 18:10).
