The program below converts a datetime object containing current date and time to different string formats.
Code:
from datetime import datetime
now = datetime.now() # current date and time
year = now.strftime("%Y")
print("year:", year)
month = now.strftime("%m")
print("month:", month)
day = now.strftime("%d")
print("day:", day)
time = now.strftime("%H:%M:%S")
print("time:", time)
date_time = now.strftime("%m/%d/%Y, %H:%M:%S")
print("date and time:",date_time)
Output after run the code:
year: 2020
month: 03
day: 31
time: 04:59:31
date and time: 03/31/2020, 04:59:31
Here, year, day, time and date_time are strings, whereas now is a datetime object.
