Hi everyone !

I have Question :

Sure I’m new in this community …

**why we are using jinja2 in our playbooks ?**  
**what can jinja2\_extensions do in our ansible.cfg ?**

e.g.

> | 
> 
> \> [defaults]
> 
> |
> | | |
> | | 
> 
> jinja2\_extensions=jinja2.ext.do
> 
> |

I can’t found an answer in officiel Doc : [[http://docs.ansible.com/ansible/intro\_configuration.html#jinja2-extensions](http://docs.ansible.com/ansible/intro_configuration.html#jinja2-extensions)] !!

tnx!
