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.

Output

Below is one acceptable solution. The idea is to “pipe” a value through several objects by overloading the right‐shift operator (>>). In our approach we define a base class (here called Pipe) that implements __rshift__. Each operator is modeled as a class with a compute(x) method that returns the new value given an input x. The Const class stores the initial value, and then each operation replaces that value with the result of its computation. Finally, the Print class prints the number before returning it. You can use the following code: ------------------------------------------------------------ #!/usr/bin/env python3 class Pipe: def __rshift__(self, other): # Call the compute method of the right-hand operator other.value = other.compute(self.value) return other class Const(Pipe): def __init__(self, x): self.value = x class Square(Pipe): def compute(self, x): return x * x class Inc(Pipe): def compute(self, x): return x + 1 class Print(Pipe): def compute(self, x): print(x) return x # Example usage: if __name__ == '__main__': Const(5) >> Square() >> Inc() >> Inc() >> Print() ------------------------------------------------------------ When you run the above program, it computes as follows: 1. Const(5) holds 5. 2. Square() squares 5 to get 25. 3. Inc() adds 1 to 25 (making 26) and then another Inc() makes 27. 4. Print() prints 27 to the screen. Any solution that uses operator overloading to “pipe” the value along in this manner is acceptable.

Output

Below is one acceptable solution. The idea is to have “pipeline‐objects” that can be chained with the >> operator. In our design each “node” is a callable that takes a number and returns a number (except Const, which ignores its argument) and the “>>” operator composes the functions. Also, when Print is chained as the last operator the chain is immediately evaluated and its result printed. (Note that even though your example uses Inc(), we needed to define Inc as well.) In the code below we define a base class (here called Pipe) and a helper class (Composed) to handle chaining: ------------------------------------------------ # Code start class Pipe: # This base class makes our objects chainable. def __rshift__(self, other): # If the right-hand object is an instance of Print, # we immediately compute the current pipeline’s result and print it. if isinstance(other, Print): result = self() # Call our chain (using __call__) other(result) return None else: # Otherwise, compose the two operations. return Composed(self, other) def __call__(self, x=None): # Each subclass must override __call__. raise NotImplementedError("Subclasses must implement __call__") class Composed(Pipe): # This class represents the composition of two pipelines. def __init__(self, first, second): self.first = first self.second = second def __call__(self, x=None): # Passing x through self.first then self.second return self.second(self.first(x)) # Now we define the requested classes: class Const(Pipe): def __init__(self, value): self.value = value def __call__(self, x=None): # Ignores the input and returns the constant value. return self.value class Square(Pipe): def __call__(self, x): return x * x class Inc(Pipe): def __call__(self, x): return x + 1 class Print(Pipe): def __call__(self, x): print(x) return x # Returning x in case it is needed later # Example usage: Const(5) >> Square() >> Inc() >> Inc() >> Print() # This produces: 5 squared is 25, then 25+1=26, then 26+1=27, and prints: 27 # Code end ------------------------------------------------ How it works: 1. Const(5) is a pipeline that always produces 5. 2. The operator “>>” composes Const(5) with Square(), producing a pipeline that (when called) produces Square(Const(5)) i.e. 25. 3. Further chaining with Inc() twice produces (26 then 27). 4. Finally, when you do “>> Print()”, the overridden __rshift__ in Pipe detects a Print instance and immediately evaluates the entire chain (via __call__) and passes the result to Print, which prints it. Any design that achieves the same behavior is acceptable.
