Here is one possible implementation of the classes you requested:
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 34 35 36 37 38 39 40 41 42 43 | class Cost: def __init__(self, value): self.value = value def __rshift__(self, other): return other(self.value) class Square: def __init__(self, value=None): self.value = value def __call__(self, value): self.value = value ** 2 return self def __rshift__(self, other): return other(self.value) class Inc: def __init__(self, value=None): self.value = value def __call__(self, value): self.value = value + 1 return self def __rshift__(self, other): return other(self.value) class Print: def __init__(self, value=None): self.value = value def __call__(self, value): self.value = value print(value) return self def __rshift__(self, other): : return other(self.value) # Example usage Cost(5) >> Square() >> Inc() >> Inc() >> Print() # prints 27 |
1 2 | cost = Cost(5) cost.square().inc().inc().print() # prints 27 |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | class Cost: def __init__(self, value): self.value = value def square(self): self.value = self.value ** 2 return self def inc(self): self.value = self.value + 1 return self def print(self): print(self.value) return self # Example usage cost = Cost(5) cost.square().inc().inc().print() # prints 27 |
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 31 32 33 34 35 36 37 38 39 40 | class Cost: def __init__(self, value): self.value = value def __rshift__(self, other): return other(self.value) class Square: def __init__(self, value=None): self.value = value def __call__(self, value): self.value = value ** 2 return self def __rshift__(self, other): return other(self.value) class Inc: def __init__(self, value=None): self.value = value def __call__(self, value): self.value = value + 1 return self def __rshift__(self, other): return other(self.value) class Print: def __init__(self, value=None): self.value = value def __call__(self, value): self.value = value print(value) return self def __rshift__(self, other): : return other(self.value) |

Here's one way you could define the `Const`, `Square`, `Inc`, and `Print` classes in Python to achieve the desired functionality:
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): return other(self.value) class Square: def __init__(self, func=None): self.func = func def __call__(self, value): if self.func is not None: value = self.func(value) return value ** 2 class Inc: def __init__(self, func=None): self.func = func def __call__(self, value): if self.func is not None: value = self.func(value) return value + 1 class Print: def __init__(self, func=None): self.func = func def __call__(self, value): if self.func is not None: value = self.func(value) print(value) |
1 | Cost(5) >> Square() >> Inc() >> Inc() >> Print() |
1 | Print()(Inc()(Inc()(Square()(Const(5))))) |
1 | Const(5).run(Square()).run(Inc()).run(Inc()).run(Print()) |

You can achieve this by creating three classes `Const`, `Square`, and `Print` with the `__rshift__` and other necessary special methods. Here's the code:
