> a = os.system('ls *JPG | wc -l')
> when i do:

> i get '0'.os.system only returns the exitcode of the command not the output. Look at the new Subprocess module and its Popen class. It can look intimidating at first but read the examples and you should find it easy enough. Altrernatively try the commands module although subprocess is intended to replace it... However you might find it easier to use the python os tools like listdir to do the job directly. a = len(os.listdir(mydir, '*JPG') Should be about right...
