Hash create

palette has asked for the wisdom of the Perl Monks concerning the following question:

Hi all

Consider I have two arrays one having the list of keys and
another array having list of values.

How can i create a hash with a single line using this two
arrays so that the keys array becomes the keys of the hash
and the values array becomes the values of the hash.

Thankyou

The technical term for Thilosophy's solution is a hash slice. It's important to know how these thingies work, precisely for your kind of issue. I asked a question about this a while ago that generated some discussion about this feature of perl: Is this a hash slice? if you want some additional back and forth to look at.	[reply]
