It looks like I really need a rest.
I've written this code ..

decision = speech_count > noise_count and True or False

If you've been using python for a long time, then you surely know that os.listdir() function returns an unsorted list of file names.

I didn't care much untill I faced a situation, in which the sorted-sequential processing of files was crucial, and I could not remember whether the previous file processing were done in sorted order. Well, luckily they were. But hey, this is a little bit annoying, isn't it? Why os.listdir() returns an unsorted list of files? Would you like to find out?
