Usage Yellowpage
A fast, searchable reference for version-pinned Python APIs and common implementation tasks.
Usage Yellowpage helps developers find Python APIs by name or task. Search terms such as “head,” “load audio,” or “resize image” return relevant functions, classes, methods, properties, and runnable recipes.
Each reference can include signatures, parameters, return values, examples, aliases, package versions, and links to upstream documentation. Search runs locally in the browser, supports filters and shareable URLs, and remains available offline after loading.
The current catalog covers 70,241 public objects and 51 verified recipes across Python 3.12, NumPy, pandas, PyTorch, Transformers, scikit-learn, SciPy, Matplotlib, librosa, Pillow, Requests, IPython, Hugging Face Hub, Tokenizers, Safetensors, gdown, and tqdm.
