Variables declared inside init function of a class

Question

Variables declared inside init function of a class can be used inside other functions of the same class
But, Variables declared inside any other function of a class cannot be used inside other functions of the same class
can u tell my why this happens?

Answer 1

That should work. Maybe you're using an outdated version of Python. @_@

Answer 2

I got it sorted out.
self was missing due to which I was not able to access that variable in other functions of same class.
but, self was present in the init function.
