Time script help sought!

I am kind of in a bit of a jam (okay a big jam) and i was hoping that someone here could give me a quick hand. I had a few pages of time calculations to do. So, i just started in on them typing them in my time calculator and writing them in by hand. Now i realize, that i really need a script to d

Re: Time script help sought!

Yes, Ultimately it will be part of a large digital archive available for researchers on site and eventually probably on-line for the New York Public Library. It is a huge undertaking and most of the soundfiles have been made. I (we) are struggling with the sheer size of the documentation Sorr

Re: Time script help sought!

Thanks for this Everyone! Trying to work with all the stuff folks are giving me on this i a have come across a problem... down the line i notice that some of the times will also have an hour as well as in H:M:S (e.g. 1:22:40) so in some cases i would need to convert H:M:S to sec and some just M:S

Re: Time script help sought!

I also notice that there is the is the 'datetime' module, which is new to version 2.3, which i now have access to. My feeling is that this will do much of what i want, but i can't get my head round the standard library reference stuff http://www.python.org/doc/lib/module-datetime.html I don't hav

Re: Time script help sought!

still working on it and also fixing the input data. I think for simplicity and consistency's sake i will have *all* time values input and output as hh:mm:ss maybe that would be easier but i have a few thousand find and replaceeseseses to do now (yes i am doing them by hand) grr... this is hard

ls files --> list packer

I would like to use the power of Python to build some list structures for me. Namely i have organized a bunch of folders that have soundfiles in them and would like Python to slurp up all the .aif/.aiff (or .wav whatever) files in a given set of directories. My friend hacked up this is perl: $fil

Re: ls files --> list packer

and one example of a slightly fancier version would be a variation that looks recursively into subdirectories and makes separate lists for each subdirectory encountered. so if i had a directory called "~/snd/" and in "~/snd/" i had: "~/snd/one/" "~/snd/two/" "~/snd/three/" each with soundfiles

Re: ls files --> list packer

cool i just tried: >>> import os >>>snd_filelist = [f for f in os.listdir('/Users/foo/snd') if >>>f.endswith('.aif')] and it worked! and will take a huge bite out of my big script ... which i make by doing an ls in the terminal and editing (boo hoo) one one lc and one import! cool.. that oth

Re: ls files --> list packer

gosh i could even use other string methods like startswith to take all the files in a given directory which i have organized with a prefix and have them stuffed in different lists ... i think ... snd_filelist = [f for f in os.listdir('/Users/foo/snd') if f.endswith('.aif') & f.startswith('r')] \

Re: ls files --> list packer

that is nice but the little further wrinkle, which i have no idea how to do, would be to have the contents of each directory packed into a different list since you have no idea before hand how many lists you will need (how many subdirs you will enounter) ... well that is where the hairy pa

time conversions [hh:mm:ss.ms <-> sec(.ms)

Hi, I was looking at python & datetime and hoping that it would already have a method/func to translate time formats. I need to translate seconds to hh:mm:ss.ms and vice versa and would like the ability to do some basic arithmetic in these formats. I think that there just has to be a package or mo
