# 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.
