Simplifying radically, you are doing:

    def __setattr__(self, attr, k):
        if attr == "var1":
            self.var1 = k

The last line here sets the var1 attribute, and that goes through your
__setattr__() method again; henct the recursion error. You need to
bypass the  __setattr__() method with something like:

self.__dict__['var1'] = k
