Fix Python – How to calculate the time interval between two time strings

I have two times, a start and a stop time, in the format of 10:33:26 (HH:MM:SS). I need the difference between the two times. I’ve been looking through documentation for Python and searching online and I would imagine it would have something to do with the datetime and/or time modules. I can’t get it to work properly and keep finding only how t….

Fix Python – How to delete last item in list?

I have this program that calculates the time taken to answer a specific question, and quits out of the while loop when answer is incorrect, but i want to delete the last calculation, so i can call min() and it not be the wrong time, sorry if this is confusing.

Fix Python – Python logging: use milliseconds in time format

By default logging.Formatter(‘%(asctime)s’) prints with the following format:
2011-06-09 10:54:40,638

where 638 is the millisecond. I need to change the comma to a dot:
2011-06-09 10:54:40.638

To format the time I can use:

however the documentation doesn’t specify how to format millis….

Fix Python – How can I parse a time string containing milliseconds in it with python?

I am able to parse strings containing date/time with time.strptime
>>> import time
>>> time.strptime(’30/03/09 16:31:32′, ‘%d/%m/%y %H:%M:%S’)
(2009, 3, 30, 16, 31, 32, 0, 89, -1)

How can I parse a time string that contains milliseconds?

Fix Python – How do I check the difference, in seconds, between two dates?

There has to be an easier way to do this. I have objects that want to be refreshed every so often, so I want to record when they were created, check against the current timestamp, and refresh as necessary.
datetime.datetime has proven to be difficult, and I don’t want to dive into the ctime library. Is there anything easier for this sort of thing….

Fix Python – In Python, how do you convert seconds since epoch to a `datetime` object?

The time module can be initialized using seconds since epoch:
>>> import time
>>> t1=time.gmtime(1284286794)
>>> t1
time.struct_time(tm_year=2010, tm_mon=9, tm_mday=12, tm_hour=10, tm_min=19,
tm_sec=54, tm_wday=6, tm_yday=255, tm_isdst=0)

Is there an elegant way to initialize a datetime.datetime object in the same way?
