Building Serverless Microservices in Python

Updating Ubuntu, installing Git and Python 3

Git will be used later on in this book:

$ sudo apt-get update
$ sudo apt-get -y upgrade
$ apt-get install git-core

The Lambda code is written in Python 3.6. pip is a tool for installing and managing Python packages. Other popular Python package and dependency managers are available, such as Conda (https://conda.io/docs/index.html) or Pipenv (https://pipenv.readthedocs.io/en/latest/), but we will be using pip as it is the recommended tool for installing packages from the Python Package Index PyPI (https://pypi.org/) and is the most widely supported:

$ sudo apt -y install python3.6
$ sudo apt -y install python3-pip

Check the Python version:

$ python --version

You should get Python version 3.6+.
