问：“循环并打印变量的内容。 ”

答：变量dict_var是一个list。循环列表，例如

- hosts: localhost
  vars:
    dict_var:
      - key1: "val1"
      - key2: "val2"
      - key3: "val3"
  tasks:
    - debug:
        var: item
      loop: "{{ dict_var }}"

给予（删节）

    "item": {
        "key1": "val1"
    }

    "item": {
        "key2": "val2"
    }

    "item": {
        "key3": "val3"
    }

问：“循环并打印字典。 ”

答：当变量是字典时，还有更多选择。例如，使用dict2items到“循环，并具有在变量密钥对值” item.key和item.value

- hosts: localhost
  vars:
    dict_var:
      key1: "val1"
      key2: "val2"
      key3: "val3"
  tasks:
    - debug:
        var: item
      loop: "{{ dict_var|dict2items }}"

给予（删节）

    "item": {
        "key": "key1",
        "value": "val1"
    }

    "item": {
        "key": "key2",
        "value": "val2"
    }

    "item": {
        "key": "key3",
        "value": "val3"
    }

下一个选项是循环字典键的列表。例如

    - debug:
        msg: "{{ item }} {{ dict_var[item] }}"
      loop: "{{ dict_var.keys()|list }}"

给予（删节）

    "msg": "key1 val1"

    "msg": "key2 val2"

    "msg": "key3 val3"
