ECMC Coding Challenge

Task

Task 1 was chosen. The problem statement can be found in ./byte-reader/README.md

Solution

The solution is coded in Python. It assumes little when dealing wth the floating point debits and credits. For financial transactions this detail would need to be worked out in the business rules.

Running the code

Ensure you have python3 installed:

On a Mac you can install it with Homebrew:

brew install python3

Then you can run with:

git clone https://github.com/2tim/ECMC.git

cd ECMC

Create a virtual environment:

If needed install the base virtualenvwrapper (http://virtualenvwrapper.readthedocs.io/en/latest/install.html):

pip3 install virtualenvwrapper

mkvirtualenv ecmc

Install the needed packages:

pip install -r requirements.txt

python3 data_reader.py

Results will be printed to the screen:

Recommendations

Update 9/26/2017:

Implemented the recommendations below. Now using the python money library for dealing with the currency.

Recommendations for dealing with floating point currency input would be to use the python-money package: https://github.com/carlospalol/money

The code would be adapted to use the library to convert the raw float64 item to a python money object. The project is mature, follows industry standards and is easy to use.
