Creating a Custom Calculator
Your task is to create a
Number class that utilizes Python's magic methods (__add__, __sub__, __mul__, __truediv__) to perform mathematical operations. However, the class needs to be robust and be able to handle various exceptions that can occur during these operations.If a division by zero is attempted, a
ZeroDivisionError should be raised.If either of the inputs cannot be converted to a number, a
ValueError should be raised.If the operator is not a string, a
TypeError should be raised.Additionally, you should implement a custom exception,
UnsupportedOperatorError that inherits from ValueError. This error should be raised if an operation is attempted that is not supported by the class. That includes __floordiv__, __mod__, __pow__, __lshift__, __rshift__, __and__, __xor__, __or__.Input | Output |
a=Number(10); b=Number(2); print(a+b); print(a/b); | 12
5 |
a=Number(10); b=Number(0); print(a/b); | Cannot divide by zero |
a=Number('ten'); b=Number(2); print(a+b); | Invalid number input |
a=Number(10); b=Number(2); print(a**b); | Unsupported operator |
a=Number(10); b=2; print(a+b); | Operator must be a Number |
