library 23.3.0 ·python
verified Jun 28, 2026

MonkeyType is a Python library that automatically generates type annotations from sampled production types. It uses Python's `sys.setprofile` hook to record the types of function arguments, return values, and yield values at runtime. Based on this collected data, it can generate stub files (`.pyi`) or apply draft type annotations directly to existing Python code. The current stable version is 23.3.0, with a history of regular updates focusing on Python version compatibility and annotation accuracy.
