[Python] How may I instantiate a class of type hint in python?

I am new to python and am coming from C# and java. I want to instantiate a class of the type provided as type hint R as following

from typing import (TypeVar, Generic)

class BaseParams(object):
def __init__(self) -> None:
self.name = 'set-in-base-class'

class ChildParams(BaseParams):
def __init__(self) -> None:
super().__init__()
self.name = 'set-in-child-class'

R = TypeVar('R', bound= BaseParams)

class MyGeneric(Generic[R]):
def __init__(self) -> None:
super().__init__()
def test(self):
r = R() # how should I instantiate R here
print(r.name)

c = MyGeneric[ChildParams]()
c.test()


something like the following C# code

class BaseParams
{
public BaseParams()
{
Name = "set-in-base-class";
}
public string Name { get; set; }
}
class ChildParams : BaseParams
{
public ChildParams()
{
Name = "set-in-child-class";
}
}
class MyGenericClass<R> where R : BaseParams, new()
{
public void test()
{
var r = new R();
Console.WriteLine(r.Name);
}
}


I've made quite a lot search on how to do that in python and all the sources refer to a situation where we provide the type in a method or something like that. I wonder if it is possible to do that at all.

would you please someone help me to have a workaround on this?
