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 is a possible implementation of the `Cost`, `Square`, and `Print` classes in Python:
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 | class Cost: def __init__(self, x): self.x = x def __rshift__(self, other): return other(self.x) class Square: def __init__(self, x=None): self.x = x def __call__(self, x=None): if x is not None: self.x = x ** 2 return self else: return self.x def __rshift__(self, other): return other(self) class Inc: def __init__(self, x=None): self.x = x def __call__(self, x=None): if x is not None: self.x = x + 1 return self else: return self.x def __rshift__(self, other): return other(self) class Print: def __init__(self, x=None): self.x = x def __call__(self, x=None): if x is not None: self.x = x print(self.x) return self |
1 | Cost(5) >> Square() >> Inc() >> Inc() >> Print() |
1 2 3 4 5 | def Inc(x=None): if x is not None: return x + 1 else: raise ValueError("Inc requires an argument") |
1 | Cost(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 31 32 33 34 35 36 37 38 | class Cost: def __init__(self, x): self.x = x def __rshift__(self, other): return other(self.x) class Square: def __init__(self, x=None): self.x = x def __call__(self, x=None): if x is not None: self.x = x ** 2 return self else: return self.x def __rshift__(self, other): return other(self) class Inc: def __init__(self, x=None): self.x = x def __call__(self, x=None): if x is not None: self.x = x + 1 return self else: return self.x def __rshift__(self, other): return other(self) class Print: def __init__(self, x=None): self.x = x def __call__(self, x=None): if x is not None: self.x = x print(self.x) return self |
