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.
To create a chainable design for the classes `Const`, `Square`, `Inc`, and `Print`, we can define each class to return an instance of itself that can be called in a chain. Here's how you can implement it:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | class Const: def __init__(self, value): self.value = value def __rshift__(self, other): return other.calculate(self.value) class Square: def calculate(self, value): self.value = value ** 2 return self def __rshift__(self, other): return other.calculate(self.value) class Inc: def calculate(self, value): self.value = value + 1 return self def __rshift__(self, other): return other.calculate(self.value) class Print: def calculate(self, value): print(value) return self # Example usage: Const(5) >> Square() >> Inc() >> Inc() >> Print() |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | class Const: def __init__(self, value): self.value = value def __rshift__(self, other): return other.calculate(self.value) class Square: def calculate(self, value): self.value = value ** 2 return self def __rshift__(self, other): return other.calculate(self.value) class Inc: def calculate(self, value): self.value = value + 1 return self def __rshift__(self, other): return other.calculate(self.value) class Print: def calculate(self, value): print(value) return self # Example usage: Const(5) >> Square() >> Inc() >> Inc() >> Print() |

To create a Python program that allows chaining operations as you've described, we'll define three classes: `Const`, `Square`, and `Print`. Each class will implement a `__rshift__` method that allows us to use the `>>` operator for chaining. Here's an implementation of your requirement:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | class Const: def __init__(self, value): self.value = value def __rshift__(self, other): # Pass the value to the next operation return other(self.value) class Square: def __call__(self, value): # Square the value return value * value def __rshift__(self, other): # Allow chaining by calling next operation with the result of squaring return other(self.value) class Inc: def __call__(self, value): # Increment the value return value + 1 def __rshift__(self, other): # Allow chaining by calling next operation with the result of incrementing return other(self.value) class Print: def __call__(self, value): # Print the final value print(value) # Example usage Const(5) >> Square() >> Inc() >> Inc() >> Print() |

To achieve the desired functionality, we can create a series of classes that support method chaining. The `Const` class will hold an initial value, while the `Square` class will square that value. The `Inc` class will increment the value by one, and the `Print` class will output the final result. Here's how you can implement the required classes:
