changing format of time duration.

[dave]

Quick question. I have to time stamps (now and now2).

now = datetime.datetime.now();
now2 = datetime.datetime.now();

now2-now1 yields me a result in 0:00:00.11221 (H:MM:SS.ssss)

I wanted to know if there is a standard python method or a quick hack
to add an extra zero in the beginning.

So the result I am looking for would be 00:00:00.11221

Try the strptime method with a suitable format, like this (untested):
delta = now2-now1
delta.strftime('%H:%M:%S.%f')

delta = now2-now1
delta.strftime('%H:%M:%S.%f')

Throws an exception:

|Traceback (most recent call last):
| File "<stdin>", line 1, in <module>
|AttributeError: 'datetime.timedelta' object has no attribute 'strftime'

What seems logical, since the documentation doesn't mention an strftime
method for timedelta.

You're right. Second try (still untested):

def nice_timedelta_str(d):
result = str(d)
if result[1] == ':':
result = '0' + result
return result

delta = now2-now1
print nice_timedelta_str(delta)
