eval of a private attribute

[Bertrand Geston]

Those work both:
--1. Instance variables------
class CObsFile:
    def __init__(self):
        self.__user="~briner/big/usr.rdb"
        self.__location="~genevay/system/location"
    def get(self,var):
        tobeEval ='self._CObsFile__'+var
        print 'toBeval: '+tobeEval
        p=eval(tobeEval)
        print 'Evaluated: '+p
        return p

p=CObsFile()
p.get('user')

--2. Class variables------
class CObsFile:
    __user="~briner/big/usr.rdb"
    __location="~genevay/system/location"
    def get(self,var):
        tobeEval = 'CObsFile._CObsFile__' + var
        print 'toBeval: '+tobeEval
        p=eval(tobeEval)
        print 'Evaluated: '+p
        return p

p=CObsFile()
p.get('user')
