Shouldn't something like this work?
from mypy_extensions import TypedDict
Details = TypedDict('Details', {'first_name': str, 'last_name': str})
DetailsSubset = TypedDict('DetailsSubset', {'first_name': str, 'last_name': str}, total=False)
defaults = {'first_name': 'John', 'last_name': 'Luther'} # type: Details
def generate(data: DetailsSubset) -> Details:
return {**defaults, **data}
I'm getting:
% mypy code.py
code.py: error: Expected TypedDict key to be string literal
Oh, and the error message is missing the line number, that could be handy to have.
I'm using mypy 0.530 and Python 3.6.2.
