command line - Running a python script on all the files in a directory

Question

I have a Python script that reads through a text csv file and creates a playlist file. However I can only do one at a time, like:

python playlist.py foo.csv foolist.txt

However, I have a directory of files that need to be made into a playlist, with different names, and sometimes a different number of files.

So far I have looked at creating a txt file with a list of all the names of the file in the directory, then loop through each line of that, however I know there must be an easier way to do it.

Answer 1

for f in *.csv; do
  python playlist.py "$f" "${f%.csv}list.txt"
done

Will that do the trick? This will put foo.csv in foolist.txt and abc.csv in abclist.txt.

Or do you want them all in the same file?
