从返回的Ansible结果遍历数组

Question

使用ansible pip模块对已安装的pip软件包进行验证，但是却难以解析返回的结果。返回的result.results提供了一个数组，并且当 changed：true

时，我基本上只需要包

    - name: test
      pip:
        name: "{{ item.package }}"
        version: "{{ item.version }}"
        state: present
        executable: /opt/Anaconda/bin/pip
      with_items:
        - "{{ authorized_packages }}"
      check_mode: yes
      register: result


    - name:
      debug:
        msg: "{{ result.results }}"

将.result.results作为数组返回，并且要在更改时== true时检索有关项目（包，版本）的信息；

            {
        "msg": {
            "changed": true,
            "msg": "All items completed",
            "results": [
                {

                    "stderr": "",
                    "stderr_lines": [],         
                }
            ]
        }
    }

尝试

    - name:
      debug:
        msg: "{{ result.results.0.item }}"
      when: result.results.0.changed == true

但是仅返回单个结果；

    {
        "msg": {
            "package": "absl-py",
            "version": "0.1.10"
        }
    }

认为我实际上找到了可能的解决方案，任何人都可以审查，验证和/或提供任何进一步的反馈或改进吗？

    - name:
      debug:
        msg: "Package:{{ item.item.package }} version:{{ item.item.version }} does not match the authorized package list"
      with_items: "{{ result.results }}"
      loop_control:
        label: '{{ item.item }}'
      when: item.changed==true
      no_log: true
