You need help to write this code below, the code should be in python.
The InteriorNode value() method should use the following steps:
Use self._leftOperand.value() to get the value of its left operand. Use self._rightOperand.value() to get the value of its right operand. self._operator contains the operator type.
The valid operator types are: "+", "-", "*", "/", and "^". Use self._operator in conditional logic to calculate the value to return.
Examples: If the operator is "+" (addition), the returned value should be: value of left operand + value of right operand If the operator is "^" (exponentiation), the returned value should be: value of left operand ** value of right operand If the operator does not equal a valid value, return 0.
