Class methods need to take 'self' as its first argument.  The reason's
because Python needs to know what 'balance' you mean --- you could make a
bunch of bank statements in your program, so statement() needs that
parameter.  When you say something like:

  a.statement()

Python will pass 'a' as the first parameter in statement.  This explains
the error message "TypeError: no arguments expected".

Good luck!
