Type hints for Bidict type

[BD103]

Hello,

I am creating a Python package that uses bidict. I'm wondering what type hinting I should assign to this data.

b: bidict[str, str] = bidict(
  {
    "H": "hydrogen",
    "C": "carbon"
  }
)

Is the bidict[str, str] accurate? Thank you.

Yes, that is correct. You can use reveal_type to have mypy confirm this for you:

# demo.py
from bidict import bidict

b = bidict({"H": "hydrogen", "C": "carbon"})
reveal_type(b)

$ mypy demo.py
demo.py:4: note: Revealed type is "bidict._bidict.bidict[builtins.str*, builtins.str*]"

What package are you creating that uses bidict?

My personal Python package uses bidict for hexadecimal conversion. You can see the work-in-progress code here if you're interested. Either way, thanks for the confirmation! :D
