orders-merge's Introduction

Orders merge

This repository is part of a Python assignment. I tried to not implement it in a functional way as much as possible (got used for it from ES6).

Prerequisites

Python 3.6.5

~~Install requirements by:~~

pip3 install -r requirements.txt

Wait - there are no requirements; it's all pure vanilla

To use just execute run.py with the required flags.

For example with the attached example files:

python run.py -o $PWD/example/orders.csv -b $PWD/example/barcodes.csv

To show top users use -t 5 with a integer as the amount for the top customers.
The unused barcodes are being showed both in the STDOUT and the log level.
Please find the log file in the project root merge.log for debug and error logs.
If not specify, a file name result.csv will be generate. you can use the -j flag for having a JSON format instead.
To execute it debug mode please use the env_param PY_ENV=DEV.
If I had time, I would've add some unitests, but as it wasn't required I allowed myself to release this without any.
Last point, Personally I would've store it in a collection base(NOSQL); But base on the 2 tables attached, I've created the following schema for 3 tables (and the little fields I had to work with)

-h, --help show this help message and exit
-b Barcodes source, --barcodes Barcodes source Path for the barcodes_source csv file
-o Orders Source, --orders Orders Source Path for the orders source csv file
-t Top customers, --top Top customers Integer of the top customers
-f Filename of the output, --filename Filename of the output Give a name for the output file (default result
-j Export to JSON, --json Export to JSON Export to JSON instead of CSV
-v, --version show program's version number and exit
-h, --help show this help message and exit
