In the previous lesson ( • Python Programming: Lesson 70 - Pass ... ), we had a chance to discuss a phenomenon called pass by value. Here, a variable fails to be updated because only a copy of its value was brought into a function. Solutions:
1. Attach the variable to be changed to an instance of a class and an instance method to increment or change it
2. Return a new value rather than constructing a void method
3. Apply the method with a list rather than a standalone variable
In this lesson, we get a good opportunity to review frozen dictionaries, inheritance, the call magic method, and other object-oriented fundamentals. This is a slower-paced conclusion to the Python curriculum.
