How can I pass variable to ansible playbook in the command line?

Question

I\'m new to ansible and wonder how to do so as the following didn\'t work

ansible-playbook -i \'10.0.0.1,\' yada-yada.yml --tags \'loaddata\' django_fixtures=\"t

Other answers state how to pass in the command line variables but not how to access them, so if you do:

--extra-vars "version=1.23.45 other_variable=foo"

In your yml file you assign these to scoped ansible variables by doing something like:

vars:
    my_version: "{{ version }}"
    my_other_variable: {{ other_variable }}

An alternative to using command line args is to utilise environmental variables that are already defined within your session, you can reference these within your ansible yml files like this:

vars:
    my_version: "{{ lookup('env', 'version') }}"
    my_other_variable: {{ lookup('env', 'other_variable') }}
