Question

I’ve got a list of dates (datetimes):

>>> print str(range)
[datetime.datetime(2011, 12, 15, 0, 0), datetime.datetime(2011, 12, 16, 0, 0), datetime.datetime(2011, 12, 17, 0, 0)]

and I’d like to format them as “%d/%m/%Y” and comma separate them, ie:

15/12/2011, 16/12/2011, 17/12/2011

At the moment I’m using map to run strftime on each of the dates like so:

>>> string = ", ".join(map(lambda x: x.strftime("%d/%m/%Y"), range))
>>> print string

which outputs:

15/12/2011, 16/12/2011, 17/12/2011

Ta dah!

It’s not the easiest to read, but it works. Is it efficient? Is it pythonic? (does that matter?)

Answer 1

map() is considered deprecated (although there are those that will argue otherwise).

", ".join(x.strftime("%d/%m/%Y") for x in daterange)
