In both cases you have an array and print does not insert any extra characters between the elements of an array. You can use join to do that however:

use strict; my @days; @days = qw(Monday Tuesday Wednesday Thursday Friday Saturday Sunday); print ((join ' ', @days), "\n"); print join ' ', qw(Monday Tuesday Wednesday Thursday Friday), "\n";

Prints:

Monday Tuesday Wednesday Thursday Friday Saturday Sunday Monday Tuesday Wednesday Thursday Friday

To see why I put the brackets in try these two lines:

print ((join ' ', @days), "x\n"); print join ' ', @days, "x\n"; #prints: Monday Tuesday Wednesday Thursday Friday Saturday Sundayx Monday Tuesday Wednesday Thursday Friday Saturday Sunday x

Note the space before the x in the second line because @days, "x\n" is a list that join acts on, rather than the paraneter for join followed by a parameter for print.
