Answers Key:

Generic 2

5 x 2 = 10

Python prescribes a convention of prefixing the name of the variable or method with single or double underscore to emulate the behavior of protected and private access specifiers.
Example: self_n2 = n2

Namespaces are containers for mapping names of variables to objects.
Example : a : =5
Here the variable 'a' is mapped to the value '5.

The process of binding a variable name with an object is called mapping = (equal to sign) is used in programming languages to map the variable and object.

Scope should be used for a variable because; it limits a variables scope to a single definition. That is the variables are visible only to that part of the code. Essentially, variables are addresses to an object in memory. When you assign a variable with := to an instance (object), you're binding (or mapping) the variable to that instance. Multiple variables can be mapped to the same instance.

Scope refers to the visibility of variables, parameters and functions in one part of a program to another part of the same program.
