For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Removing blank columns in csv file

Posted by nano (nano), 1 November 2005
Hi ,

Using the following to create a CSV (comma seperated value) file
my $delim = ",";
printf " %s%s%s%s\n" $colA,$colB,$delim, $delim,$colE;

Now i don't want to see empty columns for C, and D Does anyone know if you can hide /remove empty columns in a CSV file

Thanks ,

Hey!

Not exactly sure by 'i don't want to see empty columns for C, and D'.
Do you mean you want

A,B,E

instead of

A,B,,,E

?


As for your existing code, why not use an array, and 'join'.

Code:
my $delim=',';
my @data=($colA,$colB,$colE);
print join( $delim, @data )."\n";


A bit more flexible, and maybe does what you want.
