All the cells below have errors in syntax or in logic. A syntax error happens when the code does not correspond to Python’s rules; Python generates an error with some information about which bit of the code caused the problem. A logic error is where the code does run, but does not do what it was intended to do. Run the cells to see the error, and then fix them to work correctly.
