如何只接受 Python function 中的一些字符串？

Question

I want to make it like this:我想让它像这样：

>>> myfunc("strawberry")
ok
# myfunc only works with strawberry

I know that most people will answer with:我知道大多数人会回答：

def myfunc(something):
   if something == "strawberry":
      print("ok")

But I want to do all this in the parameter setting.但我想在参数设置中完成这一切。
Like, kind of like this:就像，有点像这样：

def myfunc(something: OnlyThese["strawberry", "cake"]:
   print("ok")

Although the code above is very incorrect, I want to see if Python already has a feature like this.虽然上面的代码很不正确，但是我想看看Python是否已经有这样的功能。

Don't believe there is a way to do what you are wanting to do without writing code in the function body.不要相信没有在 function 主体中编写代码的情况下可以做你想做的事情。
