小编AL_*_*L_1的帖子

我有一个 JSON 文件，我将其转换为具有类似内容的 Dict

{
  "a": "1",
  "b": "2",
  "c": "3"
}

我想根据那个 JSON 格式化这个字符串

"Blah {a} Blah Blah {b} {c}"

输出

"Blah 1 Blah Blah 2 3"

我没有尝试过任何东西，也没有通过谷歌搜索 ( Python how to format string based on json)找到任何东西，大多数结果只是为了漂亮地打印 JSON。

当我执行命令"/ voltiac"时,它会在控制台中输出此错误,并在"我的世界"中说"尝试执行此命令时发生内部错误".但是,当我执行命令"/ voltiac help"和"/ voltiac about"时,它们完美地工作.我试图让插件做的是当我执行命令"/ voltiac"时,它与执行"/ voltiac about"相同.

这是错误
