type hinting tuples of fixed but rather large fixed length

Question

I currently type hint a function returning tuple as follows:

FuncOutput = Tuple[nib.Nifti1Image,
                   nib.Nifti1Image,
                   nib.Nifti1Image,
                   nib.Nifti1Image,
                   nib.Nifti1Image,
                   nib.Nifti1Image,
                   nib.Nifti1Image]

Is there a way to do this in a concise manner where I can specify the length without typing it so many times?

Answer 1

No. typing.Tuple only supports typing each element or a variable number of elements.

You can use type variable.

T = TypeVar('T')
tuple7 = tuple[T, T, T, T, T, T, T]
# then you can write
FuncOutput = tuple7[nib.Nifti1Image]
