Module does not recognize Debian python package name

[atayts]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 5.5.3
• Ruby: 2.4.4p296
• Distribution: Debian 9
• Module version: 3.0.1

How to reproduce (e.g Puppet code you use)

include python

python::ensure: present
python::version: 'python3'
python::pip: present
python::pip::botstrap::version: 'pip3'

What are you seeing

An error message 'version needs to be pypy, system or a version string like '36', '3.6' or 'python3.6''

What behaviour did you expect instead

Should be working.

Any additional information you'd like to impart

The cause of a problem is in init.pp code, line 68. It precludes from using a python version 'python3' as it expects a version to be two or more digits in a row or separated by a dot. Debian package is named 'python3' where a version is a single digit, thus not passing verfication of the regexp below.

  unless $version =~ Pattern[/\A(python)?[0-9](\.?[0-9])+/,
        /\Apypy\Z/, /\Asystem\Z/, /\Arh-python[0-9]{2}(?:-python)?\Z/] {
    fail("version needs to be pypy, system or a version string like '36', '3.6' or 'python3.6' )")
  }

The fix is to replace '+' with '*' like this:

  unless $version =~ Pattern[/\A(python)?[0-9](\.?[0-9])*/,
  ...
