Selecting Elements from Lists

Selecting Elements from Lists

The list notation is identical to that for arrays - you can extract an element from an array by appending square brackets to the list and giving one or more indices:

#!/usr/bin/perl

$var = (5,4,3,2,1)[4];

print "value of var = $var\n"

This will produce following result:

value of var = 1

Similarly, we can extract slices, although without the requirement for a leading @ character:

#!/usr/bin/perl

@list = (5,4,3,2,1)[1..3];

print "Value of list = @list\n";

This will produce following result:

Value of list = 4 3 2
