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 the implementation of the Const, Square, Print classes:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | class Const: def __init__(self, value): self.value = value def __rshift__(self, other): return other(self.value) class Square: def __call__(self, value): return value ** 2 class Inc: def __call__(self, value): return value + 1 class Print: def __call__(self, value): print(value) 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 | class Const: def __init__(self, value): self.value = value def __rshift__(self, other): return other(self.value) class Square: def __call__(self, value): return value ** 2 class Inc: def __call__(self, value): return value + 1 class Print: def __call__(self, value): print(value) Cost(5) >> Square() >> Inc() >> Inc() >> Print() |
