Questions

• How do we write code for operational use?

Objectives

• Integrate git flow with working objectives.

Python Packaging

The setup.py File

Putting a setup.py file will instruct the “pip” program to try and install your local package. This will get installed with the specified

from setuptools import setup

setup(
    name="my_package_name",
    version="1.0.0",
    install_requires=["pandas", "sqlalchemy", "mycli"],
)

Installing Packages

The pip install syntax is given by pip install <location_of_package>. You can install both local and remote packages. Pip will try to find packages in the following order if not location protocol is specified :

1. PyPi
2. Custom configured PyPi servers
3. Your current working directory

pip install -e .

Create and Install a Package

1. Create a setup.py file for your python package
2. Install your package with pip

Key Points

• You can test code locally in an interactive environment like jupyter notebook

• Moving code to a version controlled python package enables sharing.
