Python to brainfuck transpiler

This tool compiles python to bytecode and then transpiles the bytecode into brainfuck.

Usage

Tested on python 3.10

./py2bf.py file1.py file2.py ...

Working example

This is about the most functionality you can get out of this so far.

print("This is an example program")

def printFeatures():
    print("Basic functions work!")

printFeatures()

def featuresWithArgs(feature):
	print(feature)

featuresWithArgs("Arguments to functions work")

variables = "And so do variables outside functions"
print(variables)

Compatibility

py2bf only supports python 3.7 and newer, for now. Information relative to python 3.11.2:
