Execute Befunge code. "beef-ex".
This is a mostly complete Befunge-93 interpreter! Befunge is an esoteric language that executes in two dimensions!
python befx.py examples/helloworld.befunge
python befx.py -f 100 examples/helloworld.befunge
python befx.py -H examples/helloworld.befunge
echo -e "3\n6\n7\n0\n" | python befx.py examples/calculator.befunge -H
Probably don't do this, but if you insist:
from befx import exec_befunge
output = exec_befunge('"!dlroW olleH">:#,_@')
print(output)
