PythonD is a 32-bit, multi-threaded, networking- and OpenGL-enabled Python interpreter for DOS and Windows.

The Python executable at the heart of PythonD has been compiled with the DJGPP 2.0.4, using GCC 3.3.2 on WindowsXP. The port is long-filename compliant and uses the same library structure as Linux and Windows ports so that third-party packages can be installed easier without import declaration modifications. Although stdout may run in background when graphics modes are engaged, PythonD always runs in a single window using a single process.

PythonD offers the very first multi-threaded POSIX scripting interpreter for DOS ever available. Threading for PythonD is provided through a very standard implementation, using PTH threads ported by Richard Dawe.
