SimpleDictFetcherTypes

Data for translating using only the default id and name placeholders.

Must be on the form {source: {id: name}}.

alias of dict[SourceType, dict[IdType, str]]

SourceToPlaceholderTranslationsMakeTypes

Data for translating using arbitrary placeholders; see PlaceholderTranslations.make()

alias of Mapping[SourceType, PlaceholderTranslations[SourceType] | pandas.DataFrame | dict[str, Sequence[Any]] | dict[IdType, str]]

class TranslateParams

Bases: TypedDict, Generic[NameType, SourceType, IdType]

Keyword arguments of Translator.translate().

Note

Does not include translatable or copy.

Motivation

Allowing these to be passed as keyword arguments causes issues with typing, especially method overloading. For example:

def func(**kwargs: Unpack[AllTranslateParams]):
   translatable = kwargs["translatable"]
   if isinstance(translatable, list) and kwargs.get(copy, True):
       raise CustomException("we don't do that here")

   else:
       # Do whatever

using AllTranslateParams is typically not as safe as:

@overload
def func(...): ...

@overload
def func(
    translatable: list, copy: Literal[False],
    **kwargs: Unpack[TranslateParams]
) -> Never: ...

def func(translatable, copy, **kwargs: Unpack[TranslateParams]):
    "Implementation as above"

since func(translatable=[], copy=False) does not behave like Translator.translate([], copy=False) would. Functions that transparently wrap Translator.translate() should probably use functools.wraps() instead.
