cop_thy     70     ijk_yuc     80     irt_hgt     80

That is not surprising. In post #1 in this thread you said you had CSV input files and used an example that used <tab> characters as the character that separates values. The code RudiC provided explicitly specified the <tab> character as the field separator.

In this post, however, there are no <tab> characters; only sequences of <space>s. And, since the number of spaces between fields is not a constant, we can't say that your field separator is a sequence of 8 <space>s or of 9 <space>s.

If you don't accurately describe your input file format, it is hard to guess at what might work with whatever random data format you decide to use when you run code that was designed to use the input format you originally specified.

PROCESSCSV.PY(1)					      Virtualization Support						  PROCESSCSV.PY(1)

NAME

       processcsv.py - process virt-top CSV files

SUMMARY

	virt-top --csv data.csv
	processcsv.py < data.csv

DESCRIPTION

       virt-top is a top(1)-like utility for showing stats of virtualized domains.

       processcsv.py is a simple Python script that post-processes the output of "virt-top --csv".

       It is used like this:

	virt-top --csv data.csv
	processcsv.py < data.csv

       The second command will overwrite the following files in the current directory:

       "global.csv"
	   This contains the global (host) statistics columns from the CSV file.

       "domainNN.csv" (multiple files)
	   For each libvirt domain ID NN, a file is created containing the per-domain statistics from the CSV file.
