strftime python

date_time = now.strftime("%m/%d/%Y, %H:%M:%S")

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() # 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.
