Operand vs. Operator

At 2:57 Kenneth says that the '+' is the 'operand'. It is actually the 'operator' and 5 and 'a' are the operands. Python is complaining that this combination of operands (int, str) cannot be used with the '+' operator. Makes even more sense if you think of operators like functions and operands as arguments (e.g. operator_+(5,'a') ). Just sayin'...
