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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
Creating a random series of numbers with perl.

Posted by kitwalker2886 (kitwalker2886), 4 December 2007
How could i use perl to create a random series of numbers say from 1 to 10 with no repetitions and all the numbers must also be used.. rand function gives only one number as the output, and also even if i use it repeatedly with different seeds how can i prevent repetition of numbers..??

Don't use rand. Just create an array of the numbers and use the List::Util module and the shuffle function:

use List::Util qw/shuffle/;  
my @numbers = (1..10);
@numbers = shuffle(@numbers);
print "@numbers";
