Generating documentation and code explainability

Whenever working with new applications or projects, it is always good practice to correlate your code with documentation. It might be in the form of a docstring that you can embed in your functions or classes so that others can invoke them directly in the development environment.

For example, the following Python class has 10 different methods for basic mathematical operations:

class Calculator:
    def add(self, x, y):
        return x + y
    def subtract(self, x, y):
        return x - y
    def multiply(self, x, y):
        return x * y
    def divide(self, x, y):
        try:
            return x / y
     ...
