Fluent calculator

A Python3 module implementing a Fluent Syntax calculator

This small module was built as an exercise for a job interview. I did not get the job. You shouldn't rely on this code! =D.

It is a calculator that uses the "fluent syntax" as instructed in the exercise.

Syntax

Both numbers and opperations are attributes of the calculator. To use it, chain them together.

Usage:

Simple operations

• kata.Cal.new.two.plus.two # returns 4
• kata.Cal.new.three.times.three # returns 9
• kata.Cal.new.three

Hundreds and Thousands

• kata.Cal.new.two.hundred.times.three # returns 600
• kata.Cal.new.one.times.two.thousand # returns 2000

Concatenating more than one operation
