Can't install python 3.5

[benigls]

I'm trying to install python 3.5 using the python_version variable from the playbook vars.

---
 - hosts: all
   sudo: yes
   user: root
   roles:
     - Stouts.python
   vars:
     python_version: [3.5, ]
     python_install: [virtualenvwrapper, ]

But it seems that it doesn't install the python 3.5 when I run it.

...
TASK: [Stouts.python | Install python] **************************************** 
ok: [000.000.000.00] => (item=2.7)
ok: [000.000.000.00] => (item=3.4)

TASK: [Stouts.python | Install python-dev] ************************************ 
ok: [000.000.000.00] => (item=2.7)
ok: [000.000.000.00] => (item=3.4)
...

I have to manually insert the 3.5 to the default/main.yml to install it.

@benigls I know this is late, but did you try python_versions (note the 's')?

@benigls
Have you tried the following?

   vars:
     python_versions: [3.5]
     python_install: [virtualenvwrapper]
