Example 1: python datetime string
import datetime
today = datetime.datetime.now()
date_time = today.strftime("%m/%d/%Y, %H:%M:%S")
print("date and time:",date_time)
Example 2: date time strftime
import datetime
date_time = datetime.datetime.now()
print(date_time)
--> '2020-10-03 15:29:54.822751'
date_time.strftime("%d/%m/%Y")
--> '03/10/2020'
date_time.strftime("%m/%d/%y")
--> '10/03/20'
date_time.strftime("%Y/%m/%d")
--> '2020/10/03'
date_time.strftime("%Y-%m-%d")
--> '2020-10-03'
date_time.strftime("%B %d, %Y")
--> 'October 03, 2020'

Example 3: python time format
The program below converts a datetime object containing current date and time to different string formats.
Code:
from datetime import datetime
now = datetime.now()
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.
