Are you sure that you are using python 3.6.6? I had to set python3.6 in environment settings for it to work

please post a proper MCVE - there's nothing named "NamedTuple" in the stdlib.

If you wish to use type annotation, you'll have to assign the value as well.
my_tenant_id: str = ""
my_first_name: str = ""
python cannot predefine a variable without assigning values.
Update: It seems python's type annotation allows declaration of class variables without values.
https://docs.python.org/3/library/typing.html#typing.NamedTuple
This is a class definition, not a variable definition. The posted code is valid.

Oh that is new for me. It seems you are correct. I read previously that pythons' type annotation is just for syntactic sugar. It doesn't add any new feature. But apparently in this case it does. Without: str
python complains that the variable is undefined, but with: str
it doesn't.
