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.

class Const:
    """Represents a constant value."""
    def __init__(self, value):
        self.value = value

    def __rshift__(self, other):
        """Overloads the >> operator to pipe the constant value to the next operation."""
        return other.process(self.value)


class Square:
    """Represents a squaring operation."""
    def process(self, value):
        """Squares the input value."""
        return value ** 2

    def __rshift__(self, other):
        """Overloads the >> operator to pipe the result to the next operation."""
        return other.process(self.process(0))  # dummy value, will be replaced


class Inc:
    """Represents an increment operation."""
    def __init__(self):
        self.value = None

    def process(self, value):
        """Increments the input value."""
        if self.value is None:
            self.value = value
        else:
            self.value += 1
        return self.value

    def __rshift__(self, other):
        """Overloads the >> operator to pipe the result to the next operation."""

class Print:
    """Represents a print operation."""
    def process(self, value):
        """Prints the input value."""
        print(value)


# Example usage:
Const(5) >> Square() >> Inc() >> Inc() >> Print()
However, this implementation has an issue: the `Inc` class needs to maintain its state between successive calls to `process`. To fix this, we can use a different approach:

class Const:
    """Represents a constant value."""
    def __init__(self, value):
        self.value = value

    def __rshift__(self, other):
        """Overloads the >> operator to pipe the constant value to the next operation."""
        return other.process(self.value)


class Square:
    """Represents a squaring operation."""
    def process(self, value):

        return value ** 2

    def __rshift__(self, other):
        """Overloads the >> operator to pipe the result to the next operation."""
        return other.process(self.process(0))  # dummy value, will be replaced


class Inc:
    """Represents an increment operation."""
    def process(self, value):
        """Increments the input value."""
        return value + 1

    def __rshift__(self, other):
        """Overloads the >> operator to pipe the result to the next operation."""
        return other.process(self.process(0))  # dummy value, will be replaced


class Print:
    """Represents a print operation."""
    def process(self, value):
        """Prints the input value."""
        print(value)


# Example usage:
result = Const(5) >> Square()
result = result >> Inc()
result = result >> Inc()
result >> Print()
But this is still not very readable. We can create a pipeline class to handle this:

        self.value = other.process(self.value)
        return self


class Const:

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

    def __rshift__(self, other):
        """Overloads the >> operator to pipe the constant value to the next operation."""
        return other >> Pipeline(self.value)


class Square:
    """Represents a squaring operation."""
    def process(self, value):
        """Squares the input value."""
        return value ** 2

    def __rshift__(self, other):
        """Overloads the >> operator to pipe the result to the next operation."""
        return other


class Inc:
    """Represents an increment operation."""
    def process(self, value):
        """Increments the input value."""
        return value + 1

        return self


# Example usage:

        self.value = other.process(self.value)
        return self


class Operation:
    """Base class for operations."""
    def process(self, value):
        raise NotImplementedError


class Const(Operation):
    """Represents a constant value."""
    def __init__(self, value):
        self.value = value

    def process(self, _):
        return self.value


class Square(Operation):
    """Represents a squaring operation."""
    def process(self, value):
        return value ** 2


class Inc(Operation):
    """Represents an increment operation."""
    def process(self, value):
        return value + 1


class Print(Operation):
    """Represents a print operation."""
    def process(self, value):
        print(value)
        return value


# Example usage:
Pipeline(5) >> Square() >> Inc() >> Inc() >> Print()
In this version, we define a base `Operation` class and have all operations inherit from it. The `Pipeline` class is used to chain operations together. This is a much cleaner and more maintainable implementation.
