How to link two python scripts

[Larz60+]

That's because f-string only works on python 3.6 and above.
change that line to:

print('numargs: {}'.format(numargs))

I will also need a much larger file to test sort.
Here's that web site I gave you again (not the ftp site): https://www.ncbi.nlm.nih.gov/genome/browse/#!/overview/
Please find a file that fits the bill, and send me the URL.

Thanks
