Welcome to RestrictedPython’s documentation!

RestrictedPython is a tool that helps to define a subset of the Python language which allows to provide a program input into a trusted environment. RestrictedPython is not a sandbox system or a secured environment, but it helps to define a trusted environment and execute untrusted code inside of it.

Supported Python versions

RestrictedPython supports CPython 2.7, 3.5, 3.6, 3.7 and 3.8. It does _not_ support PyPy or other alternative Python implementations.
