BF-Interpreter

Interpreter for minimal tape-based Turing complete language. This is how I chose to teach myself Python, instead of a "Hello world".

Language reference

> increment the data pointer (to point to the next cell to the right).

< decrement the data pointer (to point to the next cell to the left).

+ increment (increase by one) the byte at the data pointer.

- decrement (decrease by one) the byte at the data pointer.

. output the byte at the data pointer.

, accept one byte of input, storing its value in the byte at the data pointer.

[ if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command.

] if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.
