Re: exec

Show all headers | View raw

Hi,

thanks for your replies so far.

The reason to use exec is just laziness. I have quite a lot of classes
representing material data and every class has a number of parameters.
The parameter are Magnitude objects (they have a value and a unit and overloaded
special functions to correctly handle the units). I want to have getter
functions that either return the Magnitude object or just the value:

iron = Iron()
iron.rho(0) => value
iron.rho() => Magnitude object

def rho(self, uf=1):
    if uf == 1:
        return self._rho
    else:
	return self._rho.val

And because this would mean quite a lot of writing I tried to do it with exec.

With kind regards
Rolf Wester
