If a variable is assigned value or define Inside class function that is called instance variables.
Python Static Methods. It is a mixture of the class mechanisms found in C++ and Modula-3. Python class variables shared by all objects, not only in python, almost every programming languages. Memory allocation for such variables only happens once when the class is loaded in the memory. By modifying `a' using a class method though, you are essentially re-binding `a' to the class In Python `a' is considered a class variable. And if Variables declared inside Python functions then it’s Instance variable, the class can’t access directly. Classes¶.
