a class variable question

[Pierre Quentel]

In func1, _var1 = 1 creates a local variable _var1 (local to the
method), not an attribute of the instance. If you want an instance
attribute you must specify the reference to the instance by
self._var1 = 1 ; self must be passed as an attribute to func1

    def func1(self):
        self._var1 = 1

Similarly, in getvarValue :

    def getvarValue(self):
        return self._var1
