I want to create a dictionary with keys and its values such that my keys are the first two digit in the entry. In the next step i want to print the values of the keys in the desired order.
for example in the second part of the data which says
AC P62258; B3KY71; P29360; P42655; Q53XZ5; Q63631; Q7M4R4;
if i want AC to be printed i need to search this key and print the elements of this key P62258; B3KY71; P29360; P42655; Q53XZ5; Q63631; Q7M4R4;
can someone help me to build this dictionary and print the keys in the way its required.

Thanks in advance.

Hi deeptic,

Sorry to sound rude but I think the general idea of these forums is to assist you when you get stuck, not to do your work for you. Please have a go first then ask for help if you run into trouble, people are usually more willing to help someone who has tried

cheers,

In Perl, it's called a "hash" and you'll find excellent examples of all kinds in perldoc perldsc.

For the basics, I'll recommned to read perldoc perldata first.

Essentially, you do a my %hash and fill it in a loop for example with $hash{$yourkey} = $yourvalue and that's about it.

Thanks for the suggestion. I shall go through the example script and syntax of hash and try.

To OP: look up BioPerl - maybe there is a solution to your specific problem (not that you do not have to know basic things in Perl).
