Ansible regex_replace

I'm trying to capture the main version number of a variable, and to do this I'm trying to remove the numbers after the main version number:

In variable.yml:

version: 3.9.5
main_version: "{{ version | regex_replace('^.*(..)$', '')}}"

This should give me 3.9, however debug gives me nothing.

What's the correct way of doing this?

(And making sure that it would still be able to handle things such as 3.10.1, so that would return a main_version of 3.10, and also things such as 3.10.1-rcblah, and that would return a main_version of 3.10)

I guess your regexp should be something like:

'^.*(\.[0-9]*)$'

But why don't you use version_compare? http://docs.ansible.com/ansible/latest/playbooks_tests.html#version-comparison
