如何在计数之前添加一个字符串并使用ansible创建列表？

Question

我需要创建 10 个用户，每个用户有 5 个文件夹。

首先我尝试创建如下用户

    - set_fact: 
        user_lists: []
    - name: creating list of users
      set_fact:
        user_lists: "user-{{ user_lists + [ item] }}"
      with_sequence: count=10

我希望用户能够像 user-1 、user-2 ..user-10 这样创建。但它会抛出如下错误

fatal: [localhost]: FAILED! => {"msg": "Unexpected templating type error occurred on (user-{{ user_lists + [item] }}): coercing to Unicode: need string or buffer, list found"}

如何解决？

参见with_sequience。例如下面的剧本

  hosts: localhost
  tasks:
    - set_fact:
        user_lists: []
    - name: creating list of users
      set_fact:
        user_lists: "{{ user_lists + [ 'user-' ~ item ] }}"
      with_sequence: start=1 end=10
    - debug:
        var: user_lists

给出（删节）

    "user_lists": [
        "user-1",
        "user-2",
        "user-3",
        "user-4",
        "user-5",
        "user-6",
        "user-7",
        "user-8",
        "user-9",
        "user-10"
    ]
