slingshot-types 0.1.0

Typed Protocol+cast shims for common Python data science package functions

slingshot-types

Typed shims for popular Python package functions that often show up as Unknown in strict type checking.

The package uses Protocol and cast to provide stable, importable typed callables for:

• sklearn.metrics.classification_report
• sklearn.model_selection.train_test_split
• tqdm.tqdm

Install

pip install -e .

Usage

from slingshot_types import classification_report, train_test_split, tqdm

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)

for row in tqdm(rows):
    ...

report = classification_report(y_test, y_pred)

Why this exists

Some downstream codebases run strict checks (Unknown/Any bans in pyright or mypy configurations). These shims give typed import points while preserving runtime behavior.
