[Tutor] iterate over daterange
Hello I have a startdate and an enddate and I want to iterate over all days in between the two there doesn't seem to be a range function for dates?!? i.e. currently I am going through integers with something like this: = startdate = datetime.date(2006,1,1) enddate = datetime.date(2006,10,19) for i in range((enddate-startdate).days + 1): currentdate = startdate + datetime.timedelta(days=i) = this seems so 'unpythonic', there surely must be a better way, no? thx, -frank ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

[Tutor] ftp transfer - queue & retry pattern
Hello, I want to write a module that transfers a given file to a given destination with a given protocol (ftp, sftp, scp) to start out, just ftp would be sufficient the destination machines are sometimes unavailable, or the transfer fails sometimes due to connection problems I have several questions (sorry): 1) python ftplib or curl via commands.getoutput(...)? what are the benefits / drawbacks (portability is not an issue for me, and I like curl a lot) 2) Is there a simple way to create a subprocess(?) that I can dispatch my transfer jobs to from my main script. The goal is that my main script can proceed without beeing hung by the transfer process 3) that subprocess would need a queue, that collects all transfer jobs. can you give me some hints on how that could be done in python 4) the subprocess (?) would try to transfer all jobs one after another if one transfer fails, retry after a certain time period (say 2, 5, 10, 20, 40 min) and stop after maxnum retries how could I code this nicely in python without resorting to if then else etc? or is there a module that does 1)-4) out there somewhere already? thanks for any insight you might have -frank ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
