Python number-like class that remembers arithmetic operations?

Question

I\'m wondering if there exists a python module that would allow me to do something like this:

x = MagicNumber()
x.value = 3
y = 2 * (x + 2) ** 2 - 8
print y          


        

Answer 1

I think the difficulty is in "how to keep operators priority" rather than implementing a class.

I suggest to look at a different notation (like Reverse Polish Notation) that may help in getting rid of priority issues...
