I would be happy to add useful features to the srt command.
But before that I need to understand exactly what your script intend to do.
It build hybrid subtitles with mixed languages, right ?
Can you provide me 2 test subtitles to see it in action ?

Ok, I've to admit that I was too quick in sharing my code.
So yes, indeed, I wanted to have 2 languages.
Currently I'm learning a new language, it is useful to listen and read the language you are learning while having also the subtitles in your mother language...
here is my new code and 2 input files as well as the result.
They are just 2 test - files

And as you can see I had a quick look to the flavors of git hub! :-)

And can you tell me if this simpler version is working for you ?
import argparse
from pysrt import SubRipFile, SubRipItem, SubRipTime
parser = argparse.ArgumentParser(description='Merge 2 srt files.')
parser.add_argument('fin', type=str, nargs=2,
help='input file')
parser.add_argument(dest='fout', type=str, nargs=1,
help='the output file')
args = parser.parse_args()
master, slave = args.fin
result = args.fout[0]
msubs = SubRipFile.open(master, encoding='iso-8859-1')
ssubs = SubRipFile.open(slave, encoding='iso-8859-1')
rsubs = msubs + ssubs
rsubs.sort()
rsubs.clean_indexes()
rsubs.save (result, encoding='iso-8859-1')from pysrt.

This is what I did first, or at least something similar...., I'm relatively new to python, so I was adding one by one instead of '+', the sort I did like my shared code, as well as the 'clean_indexes'.
I was not happy with the output since I always get the a mixture: sometime first master then slave subtitles,
sometime the opposite,
sometime it needs up to 6 lines to display all the subtitles.
I like your solution more, it has cleaner code, it executes faster, but I prefer my version for its output.
Thanks for the challenge anyhow!
PS. I tried also your version, it suffer from the same issue, as my very initial version, at least in VLC player 2.0.1.
