Firstly , I should clarify I have no idea how to program python, I
joined this mailing list in anticipation of learning soon. And
thought I'd have a go playing around with your code and code given to
you (worst possible place to start, I'm sure)
But from the answers already given to you, this seems to work and as you
requested, in reality, this keeps your code to 1 line...
I'm sure this is wrong, and isn't what you want, but hey, Correct
working code doesn't seem to matter to you anyway...
(I think "Europe/Kiev" is Greece but I don't know)
from datetime import datetime, time, timedelta
import time
import pytz
def is_dst(zonename):
tz = pytz.timezone(zonename)
now = pytz.utc.localize(datetime.utcnow())
return now.astimezone(tz).dst() != timedelta(0)
def dst_greece():
if is_dst("Europe/Kiev") :
diff = 2
else:
diff = 3
return diff
lastvisit = (datetime.utcnow() +timedelta(hours=dst_greece())).strftime(
'%y-%m-%d %H:%M:%S' )

Is there someway to write the following line even better with the
ability to detect daylight saving time by itself so i don't have to
alter the line manually when time changes?
lastvisit = ( datetime.utcnow() + timedelta(hours=2) ).strftime(
'%y-%m-%d %H:%M:%S' ) # MySQL datetime format
Thanks.
Example:
#check if date entered as intented, format it properly for MySQL
lastvisit = datetime.strptime(lastvisit, '%d %m
%Y').strftime('%Y-%m-%d')
The above code gets the datetime string in a specific way and then
convert it to another format. All happens in one line clear and simple.
Now, in the following statement there shopuld be some way to check
for daylight saving time so i would aboiut add +2 in winter or +3
for greek summer time.
lastvisit = ( datetime.utcnow() + timedelta(hours=2) ).strftime(
'%y-%m-%d %H:%M:%S' ) # MySQL datetime format
I think + timedelta(hours=2) should be substituted with something
else but i don't with what.

this requires a function to be declared while i just want just an
argument inside timedelta( ) that will automatically detect DST or not.
No function declaration but instead something like:
lastvisit = ( datetime.utcnow() + timedelta( some_arg_here_that_can
detect greece's_DST_or_not) ).strftime) '%y-%m-%d %H:%M:%S' )
# MySQL datetime format
