Ansible vars_prompt value in menu

I have playbook

- hosts: "{{ host }}"
  connection: paramiko
  gather_facts: no
  serial: 1
  user: administrator
  vars_prompt:
    - name: host
      prompt: "select the router to change default route?\n1- Test01\n2- Test02\n"
      default: 1
      private: no

  tasks:
    - debug: msg="{{ host }}"

Inventory:

[1]
192.168.10.100

[2]
192.168.10.102

but I need inventory:

[Test01]
192.168.10.100

[Test02]
192.168.10.102

If you enter eg 1, the host variable contains 1, and I need to get Test01

Hello,

you can use python script to map these host variables else you can directly ask user to give input as Test01.

Thanks

or juts do :

hosts: "Test0{{ host }}"

but host names can be nvkz01 or prv02, then how to be?
