[Python] Python : variable type-hinted to to be a dictionary that accept list as value is also...

I am experimenting with type-hinting in python 3.12. I've declared a variable that is type-hinted to be a dictionary whose keys are string and values will be a list of string.

mydict : dict[str,list[str]] = {

}
#output : mydict ----> d:[k,t,k]
