How do I add seconds to a `datetime.time` object in Python?

Adding Seconds to datetime.time in Python

Unlike basic arithmetic operations, adding seconds to a datetime.time object requires a more nuanced approach. This is because datetime.time doesn't support direct addition of integers.

Standard Method via datetime Conversion:

The preferred method involves converting datetime.time to a full datetime object, adding seconds using datetime.timedelta, and then extracting the time value:

<code class="python">import datetime

a = datetime.datetime(100, 1, 1, 11, 34, 59)
b = a + datetime.timedelta(seconds=3)  # Days, seconds, then other fields
print(a.time())
print(b.time())</code>

Custom Function using timedelta:

Alternatively, you can create a custom function like addSecs:

<code class="python">import datetime

def addSecs(tm, secs):
    fulldate = datetime.datetime(100, 1, 1, tm.hour, tm.minute, tm.second)
    fulldate = fulldate + datetime.timedelta(seconds=secs)
    return fulldate.time()</code>

Example usage:

<code class="python">a = datetime.datetime.now().time()
b = addSecs(a, 300)
print(a)
print(b)</code>
