About Implementation

• The memory element, the tape is emulated using the python list.

• Value of ith element in the list corresponds to the value of cell i.

• A cell pointer is used to point towards the current cell.

• + and - increments the value of cell pointed by the cell pointer.

• > and < increments and decrements the cell pointer effectively, moving the tape right or left.

• Instructions in a block are executed and at the end of the execution of last instruction, value of current cell is checked, if it is 0, move on, else execute the block again.
