subclass of integers

[Zentrader]

This would accept ints, floats, and decimal types.

import decimal

class Nint(int):
    def __add__(self, x, y):
        try:
            return x+y
        except:
            return None

if __name__=='__main__':
    N=Nint()
    print N.__add__( 1, 2 )
    print N.__add__( 1, None )
    print N.__add__(decimal.Decimal("2"), decimal.Decimal("3"))
    print N.__add__(decimal.Decimal("2"), 3)
