This package contains typing stubs for for freezegun, a very small subset the Python stubs contained in the complete typeshed collection.

This collection of utilities contains tooling and templates to assist in creating releases on GitHub and publishing them on PyPI. It is designed to be used by Robot Framework and tools and libraries in its ecosystem, but can naturally be used also by other projects.

find_libpython helps find the path to the libpython dynamic library for the current Python environment. It is both a script and a Python package.

This module is inspired by GNU bash's variable expansion features. It can be used as an alternative to Python's os.path.expandvars function. A good use case is reading config files with the flexibility of reading values from environment variables using advanced features like returning a default value if some variable is not defined.
