Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

interpret

✓ from bfi import interpret

✗ from bfi import interpreter

Common misspelling; correct function is 'interpret' not 'interpreter'

execute

✓ from bfi import execute

✗ from bfi.bfi import execute

bfi is a single module; do not import from submodule 'bfi.bfi'

Run a Brainfuck program using the 'interpret' function, which returns output as a string.

from bfi import interpret # Simple Brainfuck program that prints 'Hello' program = "++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++." output = interpret(program) print(output)

bfi --version

Debug

Known issues

breakingIn v1.1.0, the 'time_limit' argument was removed from bfi.execute. Calling execute with time_limit will raise an error.

fix

Remove the time_limit argument; use a different approach (e.g., signal) to limit execution time.

affects: >=1.1.0

deprecatedThe 'bin/bfi' script was removed in v1.1.0. Use 'python -m bfi' instead.

fix

Run 'python -m bfi' instead of calling the script directly.

affects: >=1.1.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'bfi.bfi'

Incorrect import path (e.g., from bfi.bfi import interpret).

fix

Use 'from bfi import interpret' (module is bfi, not bfi.bfi).

AttributeError: module 'bfi' has no attribute 'interpret'

Typo in function name or old version (<1.0.3) may lack the function.

fix

Check spelling: 'interpret' not 'interpreter'. Update to latest version: pip install --upgrade bfi.

TypeError: execute() got an unexpected keyword argument 'time_limit'

Using time_limit argument which was removed in v1.1.0.

fix

Remove time_limit argument; use external timeout mechanism.
