Annoying Warning | process.extractOne | scorer=fuzz.token_sort_ratio |

[storesace-jorgelopes]

Recently i changed from fuzzywuzzy library to rapidfuzz.
However on this code line i get the following warning:

from rapidfuzz import fuzz, process
best_match = process.extractOne(query=unidecode(col), choices=patterns, scorer=fuzz.token_sort_ratio, score_cutoff=80.0)

Unexpected type(s): (str, list[Union[str, Any]], Union[(s1: Sequence[Hashable], s2: Sequence[Hashable], Any, processor: None, score_cutoff: Optional[float]) -> float, (s1: _UnprocessedType1, s2: _UnprocessedType2, Any, processor: (Union[_UnprocessedType1, _UnprocessedType2]) -> Sequence[Hashable], score_cutoff: Optional[float]) -> float], float) Possible type(s): (Optional[Sequence[Hashable]], Mapping[_KeyType, Optional[_StringType2]], _Scorer[Sequence[Hashable], Sequence[Hashable], float, float], Optional[float]) (Optional[Sequence[Hashable]], Iterable[Optional[_StringType2]], _Scorer[Sequence[Hashable], Sequence[Hashable], float, float], Optional[float]) (Optional[str], Mapping[_KeyType, Optional[_StringType2]], _Scorer[str, _StringType2, _ResultType, _ResultType], Optional[float]) (Optional[str], Iterable[Optional[_StringType2]], _Scorer[str, _StringType2, _ResultType, _ResultType], Optional[float])

This warning only occurs because of scorer=fuzz.token_sort_ratio. If I remove it, no warning appears.
Can it be a variable typing bug on the function header?

Quite possible that there is an error in the type hints. Can you send me a complete sample that allows me to reproduce this warning? What's the tool you use for the type checking?

[storesace-jorgelopes]

The sample to reproduce is the code i sent previously:

from rapidfuzz import fuzz, process
best_match = process.extractOne(query=unidecode(col), choices=patterns, scorer=fuzz.token_sort_ratio, score_cutoff=80.0)

I use PyCharm from JetBrains so i assume its the default type check that is being used.

I am asking because this is no complete sample. This sample would raise the following warnings:

• unidecode doesn't exist
• col doesn't exist
• patterns doesn't exist

I see...
Here's another example:

best_match = process.extractOne(
query="val",
choices=["lote", "lot", "data validade", "val", "validade", "iec"],
scorer=fuzz.token_sort_ratio,
score_cutoff=80.0)

Unexpected type(s): (str, list[str], Union[(s1: Sequence[Hashable], s2: Sequence[Hashable], Any, processor: None, score_cutoff: Optional[float]) -> float, (s1: _UnprocessedType1, s2: _UnprocessedType2, Any, processor: (Union[_UnprocessedType1, _UnprocessedType2]) -> Sequence[Hashable], score_cutoff: Optional[float]) -> float], float) Possible type(s): (Optional[Sequence[Hashable]], Mapping[_KeyType, Optional[_StringType2]], _Scorer[Sequence[Hashable], Sequence[Hashable], float, float], Optional[float]) (Optional[Sequence[Hashable]], Iterable[Optional[str]], _Scorer[Sequence[Hashable], Sequence[Hashable], float, float], Optional[float]) (Optional[str], Mapping[_KeyType, Optional[_StringType2]], _Scorer[str, _StringType2, _ResultType, _ResultType], Optional[float]) (Optional[str], Iterable[Optional[str]], _Scorer[str, str, _ResultType, _ResultType], Optional[float])

I can reproduce the warning in pycharm. This works as expected in mypy and pyright. I can't see anything wrong with the type hints either. So I assume some of these more advanced type hinting features just don't work as expected in pycharm. If there is a way to provide different type hints for pycharm we could make them a lot more lax. However I am not aware of any way to detect that pycharm is used for the type checking.
