How do you create a Perl module?

Question

How do you write a module for Perl? In Python you can use:

# module.py
def helloworld(name):
    print \"Hello, %s\" % name

# main.py
import module
module.         


        

Answer 1

An "exact" equivalent of your Python example in Perl would look like this:

# MyModule.pm
package MyModule;

sub helloworld { 
    my ( $name ) = @_;
    print "Hello, $name\n";
}

1;

# main.pl
use MyModule;
MyModule::helloworld( 'Jim' );
