为什么 Jinja2 将字符串渲染为“on”？为布尔值 True？

我将 Jinja2 与 YAML 结合使用，并具有以下结构：

{%- set example = [ (20, "on"), (40, "off")] %}

- name: example_yaml
    loop:
      {%- for value, state in example %}
        - TheNumber: {{ value }}
          TheState: {{ state }}
      {%- endfor %}

呈现第一个循环时，TheNumber 与 20 是正确的，但 TheState 结束是True。我查看了文档并尝试添加像这样的字符串过滤器：

{{ state | string }}

但这也不起作用。我还尝试将字符串 "on" 切换为 "StateShouldBeOn" 等其他内容以进行测试。这样我就得到了我所期望的TheState = "StateShouldBeOn"。

我的问题是，为什么“on”呈现为布尔值？

I'm using Jinja2 with YAML and have the following structure:

{%- set example = [ (20, "on"), (40, "off")] %}

- name: example_yaml
    loop:
      {%- for value, state in example %}
        - TheNumber: {{ value }}
          TheState: {{ state }}
      {%- endfor %}

When the first loop is rendered, TheNumber is correct with 20, but TheState ends up being True. I've looked through the documentation and have tried adding a string filter like this:

{{ state | string }}

But that did not work either. I have also Tried switching the string "on" to something else like "StateShouldBeOn" just to test with. With that I get what I expect TheState = "StateShouldBeOn".

My question is, why is it that "on" renders to a boolean value?
