Re: Use self.vars in class.method(parameters, self.vars)

Show all headers | View raw

I think you did a typo

it is

def foo2(self, len = self._myvar):
        while i<  len:
	 dosomething

You forget '.' dot between self and _myvar
By the way in the function header you have only one '_'
and in the init you have 2 '_'.
Be careful that's not the same variable and behavior in case you want
to access it.
