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.
Here's a solution that implements a chain of operations using classes:
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 | class Chain: def __init__(self, value): self.value = value def __rshift__(self, other): return other(self.value) class Const(Chain): def __init__(self, value): super().__init__(value) class Square: def __call__(self, value): return Chain(value * value) class Inc: def __call__(self, value): return Chain(value + 1) class Print: def __call__(self, value): print(value) return Chain(value) # Example usage: # Const(5) >> Square() >> Inc() >> Inc() >> Print() # Prints 27 |

I extracted the following code from that output:
