Hi
I can get the standard list slicing to work. But what about getting
the result of a list slice to an interpolated string or a range
interpolated.
In beginning perl Simon uses this example
#!/usr/bin/perl
# multilist.plx
use warnings;
use strict;
my $mone; my $mtwo;
($mone, $mtwo) = (1, 3);
print (("heads ", "shoulders ", "knees ", "toes ")[$mone, $mtwo]);
print "\n";
which is fine but say I wanted the print result to be: " I am touching
my shoulders and toes" rather than (shoulders toes)
Use printf:
printf(
"I am touching my %s and %s\n",
(("heads ", "shoulders ", "knees ", "toes ")[$mone, $mtwo])
);
I tried to create a list variable and then return the output of the
list interpolated but not getting expected result.
For example using months
#!/usr/bin/perl
use strict;
use warnings;
#my $summer = (0,1,2);
#my $winter = (5,6,7);
qw|
January February March
April May June
July August September
October November December
|[(my @summer = (0,1,2)), (my @winter = (5,6,7))];
print "My Summer months @summer and my winter months @winter \n";
This returns the array 0,1,2 not the slice from the list.
This works:
my @months = qw(January February March April May June July
August September October November December );
my @summer = @months[0,1,2];
my @winter = @months[5,6,7];
