For 2023 - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
Column alignment

Posted by hycheah (hycheah), 17 October 2006
How do I print out columns and align them nicely?

huiyan        100
nate        50
katherine        80

which should be printed out like this:

huiyan             100
nate                 50
katherine           80

I tried
   print "$name\t$savings\n";
but it doesn't work. So does
   printf "%s %5d\n", $name, $savings;

I don't want my data to looked scattered.

Try replacing the %s which means 'a string with %20s, which means 'a string with a minimum width of 20 character positions' and is space filled.   Change the number 20 to suit what you need.   Make it %-20s if you want to left justify the text within the 20 positions.
