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 Python implementation that allows you to chain operations as you described:
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 | class Const: def __init__(self, value): self.value = value def __rshift__(self, other): other.value = self.value return other class Square: def __init__(self): self.value = None def __rshift__(self, other): if self.value is not None: other.value = self.value ** 2 return other class Inc: def __init__(self): self.value = None def __rshift__(self, other): if self.value is not None: other.value = self.value + 1 return other class Print: def __init__(self): self.value = None def __rshift__(self, other): print(self.value) return other # Example usage Const(5) >> Square() >> Inc() >> Inc() >> Print() |
1 2 3 4 5 | # Example 1: Different chain of operations Const(3) >> Square() >> Inc() >> Print() # Will print 10 # Example 2: Multiple increments Const(5) >> Inc() >> Inc() >> Inc() >> Print() # Will print 8 |
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 | class Const: def __init__(self, value): self.value = value def __rshift__(self, other): other.value = self.value return other class Square: def __init__(self): self.value = None def __rshift__(self, other): if self.value is not None: other.value = self.value ** 2 return other class Inc: def __init__(self): self.value = None def __rshift__(self, other): if self.value is not None: other.value = self.value + 1 return other class Print: def __init__(self): self.value = None def __rshift__(self, other): print(self.value) return other |
