Jukka Lehtosalo began work on it in 2012 while at the University of Cambridge Computer Laboratory as a PhD student, borrowing ideas from his earlier Alore language and from gradual typing research. The project grew from an experiment in adding an optional static type system to Python-like code into the best-known standalone checker for ordinary Python programs. ### Project history The technical turning point was the standardization of Python type hints. PEP 484 defines the syntax and goals for type annotations in Python, explicitly naming offline type checkers such as mypy as a primary use case while keeping Python dynamically typed and type hints optional. The mypy blog described the first PEP 484 draft as heavily inspired by mypy, and later mypy versions implemented the PEP 484 annotation model used in Python codebases, editors, and CI systems. ### How it is used Dropbox became a major adoption story and development home for mypy. A Dropbox engineering writeup describes its gradual migration to static checking across millions of lines of Python, calling mypy likely the most popular standalone Python type checker and noting that the core team was employed by Dropbox. In day-to-day use, developers add annotations in source files or stubs, run the `mypy` command to find type errors without executing the program, use `dmypy` for daemonized checks, and use helpers such as `stubgen`, `stubtest`, and `mypyc` for typing ecosystem work. Package managers ship it as a developer tool for Python projects that want static analysis without changing Python's runtime model. ### Sources - - - - - - - - ## Security Notes No matching local secret-handling manifest was found for mypy. Nucleus package metadata is still published here so future coverage has a stable package URL. ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Configuration files - Unix: mypy.ini, .mypy.ini, pyproject.toml, setup.cfg, $XDG_CONFIG_HOME/mypy/config, ~/.config/mypy/config, ~/.mypy.ini ## Source Database Details -
