Prev: Iterating over more than one array in parallel

Z as in zip

Note! This site is about Perl 6.
If you are looking for a solution for the current production version of Perl 5, please check out the Perl 5 tutorial.

The Z infix operator version of the zip function allows the parallel use of two lists.

Or that of more:

tutorial/arrays/z_on_more.p6

#!/usr/bin/env perl6
use v6;

my @operator  = <+ - *>;
my @left      = <1 2 3>;
my @right     = <7 8 9>;

for @left Z @operator Z @right -> $a, $o, $b {
    say "$a $o $b";
}

Output:

tutorial/arrays/z_on_more.p6.out

1 + 7
2 - 8
3 * 9
