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

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?

Fix Python – Iterating through a range of dates in Python

I have the following code to do this, but how can I do it better? Right now I think it’s better than nested loops, but it starts to get Perl-one-linerish when you have a generator in a list comprehension.
day_count = (end_date – start_date).days + 1
for single_date in [d for d in (start_date + timedelta(n) for n in range(day_count)) if d <= end_d....

Fix Python – Creating a range of dates in Python

I want to create a list of dates, starting with today, and going back an arbitrary number of days, say, in my example 100 days. Is there a better way to do it than this?

a =
numdays = 100
dateList = []
for x in range (0, numdays):
dateList.append(a – datetime.timedelta(days = x))
print dateList


Fix Python – Adding days to a date in Python

I have a date “10/10/11(m-d-y)” and I want to add 5 days to it using a Python script. Please consider a general solution that works on the month ends also.
