Example 1: convert into date python
from datetime import datetime
datetime_str = '09/19/18 13:55:26'
datetime_object = datetime.strptime(datetime_str, '%m/%d/%y %H:%M:%S')
print(type(datetime_object))
print(datetime_object) # printed in default format
Example 2: 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 3: string to datetime convert
import datetime
date_time_str = '2018-06-29 08:15:27.243860'
date_time_obj = datetime.datetime.strptime(date_time_str, '%Y-%m-%d %H:%M:%S.%f')
print('Date:', date_time_obj.date())
print('Time:', date_time_obj.time())
print('Date-time:', date_time_obj)
Example 4: datetime to string python
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)

Example 5: csharp datetime string format
DateTime.Now.ToString("MM/dd/yyyy HH:mm:ss")
Example 6: 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.
