How can I filter 'stdout_lines'?

I am trying to filter out a line out of Ansible stdout_lines result. The output script is then sent by email. Cannot get the display format I wanted. Required output format:

host1:

Service1: Status

Service2: Status

host2:

Service1: Status

Service2: Status

My playbook is below:

- hosts: [MyServers]

  tasks:

  - name: Run a script
    win_shell:  Get-Service -DisplayName Hyper-V* | Select-Object DisplayName, Status
    register: result

  - name: Debug_services
    debug:
      msg: = {{ result }}

  - name: Send e-mail
    run_once: true
    mail:
        host: test.example.com
        port: 1111
        to: test@example.com
        subject: Check_Service_State
        subtype: html
        body: " 
        {% for item in play_hosts %}
        {{ item }}: {{ hostvars[item]['result']['stdout_lines'] }}. <br>  
        {% endfor %}
        "
        from: test@example.com
      
    ignore_errors: yes  
    delegate_to: localhost

My output format looks like:

host1: ['', 'DisplayName Status', '----------- ------', 'Hyper-V Host Compute Service Running', 'Hyper-V Guest Service Interface Stopped', 'Hyper-V Heartbeat Service Stopped', 'Hyper-V Data Exchange Service Stopped', 'Hyper-V Guest Shutdown Service Stopped', 'Hyper-V Time Synchronization Service Stopped', 'Hyper-V PowerShell Direct Service Stopped', 'Hyper-V Volume Shadow Copy Requestor Stopped', 'Hyper-V Virtual Machine Management Running', '', ''].
host2: ['', 'DisplayName Status', '----------- ------', 'Hyper-V Host Compute Service Running', 'Hyper-V Guest Service Interface Stopped', 'Hyper-V Heartbeat Service Stopped', 'Hyper-V Data Exchange Service Stopped', 'Hyper-V Guest Shutdown Service Stopped', 'Hyper-V Time Synchronization Service Stopped', 'Hyper-V PowerShell Direct Service Stopped', 'Hyper-V Volume Shadow Copy Requestor Stopped', 'Hyper-V Virtual Machine Management Running', '', ''].  

How can I filter this list correctly or how elegantly can it be done with another script construction?

According your initial description

> win_shell: Get-Service -DisplayName Hyper-V* | Select-Object DisplayName, Status

I understand that you like to gather facts about a Windows Remote Node, specifically the status of certain services.

> How elegantly can it be done?

By using win_service_info module – Gather information about Windows services
Note which will provide "A list of service(s) that were found based on the criteria". There will be a list with elements=dictionary returned, so there is no need for filtering stdout_lines, parsing the output, writing scripts, etc.

> win_shell: Get-VirtualDisk | Select-Object FriendlyName, HealthStatus

Since for most tasks and resources dedicates modules are available, for additional facts like Get-VirtualDisk you may have a look into win_disk_facts module – Show the attached disks and disk information of the target host.
