<a href="http://docs.python.org/library/time.html#time.timezone" rel="noreferrer">time.timezone</a>:

<pre><code>import time

print -time.timezone
</code></pre>

It prints UTC offset in seconds (to take into account Daylight Saving Time (DST) see <a href="http://docs.python.org/library/time.html#time.altzone" rel="noreferrer">time.altzone</a>:

<pre><code>is_dst = time.daylight and time.localtime().tm_isdst &gt; 0
utc_offset = - (time.altzone if is_dst else time.timezone)
</code></pre>

where utc offset is defined via: "To get local time, add utc offset to utc time."

In Python 3.3+ there is <a href="http://docs.python.org/3/library/time.html#time.struct_time" rel="noreferrer"><code>tm_gmtoff</code> attribute</a> if underlying C library supports it:

<pre><code>utc_offset = time.localtime().tm_gmtoff
</code></pre>

Note: <code>time.daylight</code> may give a wrong result in <a href="http://bugs.python.org/issue1647654" rel="noreferrer">some edge cases</a>.

<code>tm_gmtoff</code> is used automatically by datetime if it is available on Python 3.3+:

<pre><code>from datetime import datetime, timedelta, timezone

d = datetime.now(timezone.utc).astimezone()
utc_offset = d.utcoffset() // timedelta(seconds=1)
</code></pre>

To get the current UTC offset in a way that workarounds the <code>time.daylight</code> issue and that works even if <code>tm_gmtoff</code> is not available, <a href="https://stackoverflow.com/a/3168139/4279">@jts's suggestion</a> to substruct the local and UTC time can be used:

<pre><code>import time
from datetime import datetime

ts = time.time()
utc_offset = (datetime.fromtimestamp(ts) -
 datetime.utcfromtimestamp(ts)).total_seconds()
</code></pre>

To get UTC offset for past/future dates, <code>pytz</code> timezones could be used:

<pre><code>from datetime import datetime
from tzlocal import get_localzone # $ pip install tzlocal

tz = get_localzone() # local timezone 
d = datetime.now(tz) # or some other local date 
utc_offset = d.utcoffset().total_seconds()
</code></pre>

It works during DST transitions, it works for past/future dates even if the local timezone had different UTC offset at the time e.g., Europe/Moscow timezone in 2010-2015 period.

I tried JTS' answer first, but it gave me the wrong result. I'm in -0700 now, but it was saying I was in -0800. But I had to do some conversion before I could get something I could subtract, so maybe the answer was more incomplete than incorrect.
