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

# Understanding the Problem You need me to implement a set of Python classes that can be chained together with the `>>` operator to form a pipeline of operations. In the example, `Const(5) >> Square() >> Inc() >> Inc() >> Print()` should result in printing 27 to the screen. Breaking down the operations: - `Const(5)` starts with the value 5 - `Square()` squares it to get 25 - `Inc()` increments it to 26 - `Inc()` increments it again to 27 - `Print()` prints the final value # Solution

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

class Square:
    def __call__(self, value):
        result = value ** 2
        
        class Result:
            def __rshift__(self, other):
                return other(result)
        
        return Result()

class Inc:
    def __call__(self, value):
        result = value + 1
        
        class Result:
            def __rshift__(self, other):
                return other(result)
        
        return Result()

class Print:
    def __call__(self, value):
        print(value)
        
        class Result:
            def __rshift__(self, other):
                return other(value)
        
        return Result()
# Explanation 1. Each class is designed to be part of a pipeline where data flows from left to right. 2. The `Const` class: - Stores an initial value - Implements `__rshift__` to pass its value to the next operation 3. The operation classes (`Square`, `Inc`, `Print`): - Implement `__call__` to perform their specific operation on the input value - Return a Result object that has a `__rshift__` method to continue the pipeline 4. When you chain them together with `>>`, each operation receives the result of the previous operation, processes it, and passes the new result to the next operation. When you run `Const(5) >> Square() >> Inc() >> Inc() >> Print()`, it will indeed print 27 to the screen.

## Explanation Let's trace through how this works with your example: 1. `Const(5)` creates an operation object holding the value 5 2. `Const(5) >> Square()` applies the square operation, resulting in value 25 3. `... >> Inc()` increments to 26 4. `... >> Inc()` increments to 27 5. `... >> Print()` prints 27 to the screen The key elements of this implementation: - Each operation class inherits from `Op`, which provides the core pipeline functionality - The `__rshift__` method (>>) is overridden to pass values down the pipeline - Each operation implements its own `apply()` method for its specific transformation - The `Print` class handles printing in multiple ways to ensure the value gets printed When we write `Const(5) >> Square() >> Inc() >> Inc() >> Print()`, the pipeline executes from left to right, and the final value of 27 gets printed to the screen.
