A (technically) simple language that compiles to CPython bytecode. DISCLAIMER: this project is just for fun, please don't use it for anything serious, thanks.

CPython 3.4 or any other Python VM with equivalent bytecode (like PyPy3).

pip3 install git+https://github.com/pyos/dg

python -m dg
python -m dg file.dg argument1 argument2
python -m dg <<< 'print "Hello, World!"'
echo 'print "Hello, World!"' > dg_module.dg; python -c 'import dg, dg_module'

python -m pytest                # Compare against expected behaviour
python -m pytest --set-expected # Writes the new expected behaviour
