hello,
i have a question according 'self'. I have setup a small simple scenario
to simulate the problem.
This following small program works fine ..
when i now remove the 'self' within the method 'set_foo' it does not set
the values any more.
so my 1st question is: why doesnt the 'set_foo' method calls the 'x'
method if i remove the self?
THE INTERESTING THING: 'get_foo' works with 'x' and 'self.x'
and the 2nd question: when should i use self now and when not and why is
there this strange behavoir?
thanks for looking into this.
