Script to create bilingual tab delimited terminology files from multilingual table

So I have a table with entries for 20 languages approx. and another one with many more languages. I suppose the script already exixts.

What is needed is say:

read in column A and column B in file <something.csv>

add to file <something.txt>

skip if field A or B in line are empty and go ahead with next line

stop at eof <something.csv>

Now I have a script to create .kvtml file in Python which I know how to modify for this stuff, but there is some kind of condition in there that creates me problems ... I don't know what to exclude to not write the lesson numbers - these are required and not really being able to program I don't find that line ... hmmm

But I suppose there is already a python script that is able to do what I need, just create a tab delimited txt files which has entries like these

dog\tHund
house\tHause
...


Ok ... now thanks to the #pootle chat I have a way to do this from comand line and so this can go into the .sh file :-)

On comand line write:

cut -s -f2,3 originalfilename > targetfilename

I know there are more elegant solutions, but for me: the result counts and well :-)))
