Python in the world of retail and mail order

At Blue Yonder a lot of different python packages, provided by the community, as well as our own self-written packages, are used in order to provide flexible solutions to our problems.

In this talk I’ll present a walkthrough of a generic python application example for demand and purchase order quantity calculations, putting together those packages in an orderly way. The example will feature real world problems derived from hands-on experience with our retail and mail order customers. Additionally the talk addresses the subjects of testing, configuring, parallelising and deploying the code.

Packages used in this talk are :

• pytest http://pytest.org/latest/
• voluptuous https://github.com/alecthomas/voluptuous
• redis https://pypi.python.org/pypi/redis/
• SciPy http://www.scipy.org/
• scikit-learn http://scikit-learn.org/stable/
• pandas http://pandas.pydata.org/
