What does this mean 'Parameters to generic types must be types'?

I have a function signature:

keyword_extraction(content: str, channels=List[Channel.Game]){
   ...
}

But I got an error message:

Parameters to generic types must be types.

In my case, the List is of type Channel.Game, where Channel is an Enum in Python. What does it complain it?

If Channel is an Enum surely Channel.Game is a *value*? Can you give a [mre]? – jonrsharpe Jan 08 '21 at 23:06
If `Channel` is an enum, then `Game` is one of its values. You need it to be `List[Channel]` – Tomerikoo Jan 08 '21 at 23:07
@Tomerikoo, but I need to assign a default value. If I just use List[Channel], the default value won't be Channel.Game. How to deal with this? – marlon Jan 08 '21 at 23:19
But you mixed types and values... Did you mean `channels: List[Channel] = Channel.Game`? – Tomerikoo Jan 08 '21 at 23:22
Yes. That is true. – marlon Jan 08 '21 at 23:34
