Query

Write a python class Const, Square, Print so that I can write, for example, Cost(5) >> Square() >> Inc() >> Inc() >> Print() and the resulting python program will print 27 to the screen.

Output

To solve this problem, we need to create Python classes that allow chaining operations using the `>>` operator such that the sequence `Const(5) >> Square() >> Inc() >> Inc() >> Print()` results in printing `27` to the screen. The key is to design each class to process a value and pass it along the chain using operator overloading. ### Approach 1. **Class Design**: Each class (`Const`, `Square`, `Inc`, `Print`) will handle a specific operation. The `Const` class initializes the value, while `Square`, `Inc`, and `Print` process the value in sequence. 2. **Operator Overloading**: The `>>` operator is overloaded using the `__rshift__` method in the `Const` class to pass the current value to the next processing step. 3. **Processing Steps**: Each processing step (`Square`, `Inc`, `Print`) will have a `process` method that modifies the value and returns it (except `Print`, which prints the value). ### Solution Code

class Const:
    def __init__(self, value):
        self.value = value

    def __rshift__(self, other):
        return Const(other.process(self.value))

class Square:
    def process(self, value):
        return value ** 2

class Inc:
    def process(self, value):
        return value + 1

class Print:
    def process(self, value):
        print(value)
        return value

# Example usage
Const(5) >> Square() >> Inc() >> Inc() >> Print()
### Explanation 1. **Const Class**: This class initializes with a value and overloads the `>>` operator. When `>>` is used, it passes the current value to the next processing step (another class instance) and wraps the result in a new `Const` instance. 2. **Square Class**: The `process` method squares the input value and returns the result. 3. **Inc Class**: The `process` method increments the input value by 1 and returns the result. 4. **Print Class**: The `process` method prints the input value and returns it to allow further chaining (though in this example, it is the last step). When the code `Const(5) >> Square() >> Inc() >> Inc() >> Print()` is executed: - `Const(5)` initializes the value to 5. - `Square()` processes 5 to 25. - The first `Inc()` processes 25 to 26. - The second `Inc()` processes 26 to 27. - `Print()` outputs 27 to the screen. This approach ensures that each step processes the value sequentially and passes it along the chain, resulting in the desired output.
