I have the below code where it is adds a header to my file. you can see in the header it adds; 'name', 'date' and 'time'.

what i am trying to attempted next is to add another line in the header called 'AddedTime'. this field needs to add 15 mins on top of the current time and output it out into the 'AddedTime' header.

Python code.

stamp = datetime.datetime.now()
Year = str(stamp)[:4]
Month = str(stamp)[5:7]
Day = str(stamp)[8:10]
Hour = str(stamp)[11:13]
Minutes = str(stamp)[14:16]
Seconds = str(stamp)[17:18]
Date = Year + Month + Day
time = Hour + ':' + Minutes + ':' + Seconds

file = 'file.txt'
header_names = 't1':'Test1', 't2': 'Test2','t3':'Test3'
with open(file, 'w', newline='') as f:
 f.seek(0,0)
 f.writelines("Name: ", file)
 f.writelines("Date: ",date)
 f.writelines("Time: ",time)
 w = csv.DictWriter(f, fieldnames=header_names.keys(), restval='', 
 extrasaction='ignore')
 w.writerow(header_names)
 for doc in res['test']['test']:
 my_dict = doc['test']
 w.writerow(my_dict)
 f.seek(0,2)
 f.writelines("This is generated using Python")

Current file looks like below. - file.txt

header
Name:file.txt
Date:20190321
Time:9:15:00

data
Test1,Test2,Test3
Bob,john,Male
Cat,Long,female
Dog,Short,Male
Case,Fast,Male
Nice,who,Male

Ideal file output - file.txt

header
Name:file.txt
Date:20190321
Time:09:15:00
AddedTime:09:30:00

data
Test1,Test2,Test3
Bob,john,Male
Cat,Long,female
Dog,Short,Male
Case,Fast,Male
Nice,who,Male

any help will be appreciated.

import datetime
print(datetime.datetime.now() + datetime.timedelta(minutes=15))

Yes it's quite simple with datetime.timedelta, just do an addition of 15 mins, and you could use strftime to format the datetime output.

addedTime = (stamp + datetime.timedelta(minutes=15)).strftime('%H:%M:%S')
