I’m not getting the same thing happen.

The ansible\_host var is expecting a fqdn or ip so should just show like below.  
what version of ansible are you using?

# cat test

test1 ansible\_host=10-1

test2 ansible\_host=“10-1”

test3 ansible\_host=‘10-1’

ansible-inventory -i test --list

{

“\_meta”: {

“hostvars”: {

“test1”: {

“ansible\_host”: “10-1”

},

“test2”: {

“ansible\_host”: “10-1”

},

“test3”: {

“ansible\_host”: “10-1”

}

}

},

“all”: {

“children”: [

“ungrouped”

]

},

“ungrouped”: {

“hosts”: [

“test1”,

“test2”,

“test3”

]

}

}

I think the python version is the problem here.  
I see the behavior with ansible using python 3.6.x on a host system or in the current awx container (12.0.0 or 13.0.0). AWX uses python 3.6 currently.  
When I use ansible with Python 3.8.x, I see the correct result like you described.

You're probably right. I see the problem in FreeBSD too

Reported to the AWX project: [https://github.com/ansible/awx/issues/7448](https://github.com/ansible/awx/issues/7448)

Reason for the behaviour with python 3.6: [https://github.com/ansible/ansible/issues/70323#issuecomment-650176138](https://github.com/ansible/ansible/issues/70323#issuecomment-650176138)
