You can use time.localtime and look at the tm_isdst flag in the return value.
>>> import time
>>> time.localtime()
(2010, 5, 21, 21, 48, 51, 4, 141, 0)
>>> _.tm_isdst
0
Using time.localtime(), you can ask the same question for any arbitrary time to see whether DST would be (or was) in effect for your current time zone.

It may be a bit more clear to use time.daylight property. It will return a non-zero result if your current time zone has DST.

@brian buck: That's different though. For a given time zone,time.daylightis constant because a daylight zone either exists or it doesn't. On the other hand, thetm_isdstflag reflects whether the given time is within the DST start and end dates.

it should be_.tm_isdst > 0(-1value is possible).

Ahhh! I hate these sort of answers for Python questions as it is a command line example that does not illuminate (to me) how to put this into a function. (My naive effort to try time.localtime().tm_isdst does not work.) So I will plumb further and augment the answer.

Expanding @Greg Hewgill's answer above, plus coping with local timezone (with help of pip install tzlocal), you get:
import time
from datetime import datetime, timedelta
from tzlocal import get_localzone
def to_local(dt):
"""From any timezone to local datetime - also cope with DST"""
localtime = time.localtime()
if localtime.tm_isdst:
utctime = time.gmtime()
hours_delta = timedelta(hours=(localtime.tm_hour - utctime.tm_hour))
dt = dt - hours_delta
return dt.replace(tzinfo=get_localzone())
