1The program below converts a datetime object containing current date and time to different string formats.
2
3Code:
4
5from datetime import datetime
6
7now = datetime.now() # current date and time
8
9year = now.strftime("%Y")
10print("year:", year)
11
12month = now.strftime("%m")
13print("month:", month)
14
15day = now.strftime("%d")
16print("day:", day)
17
18time = now.strftime("%H:%M:%S")
19print("time:", time)
20
21date_time = now.strftime("%m/%d/%Y, %H:%M:%S")
22print("date and time:",date_time)
23
24Output after run the code:
25year: 2020
26month: 03
27day: 31
28time: 04:59:31
29date and time: 03/31/2020, 04:59:31
30
31Here, year, day, time and date_time are strings, whereas now is a datetime object.
