Azure CLI

Azure CLI, or Azure Command Line Interface, is a set of commands used to create and manage Azure resources. It is a cross-platform command-line tool that's available for Windows, macOS, and Linux and can be run in the Azure Cloud Shell directly from a web browser.

Azure CLI is designed to be easy to learn and get started with but powerful enough to manage your entire Azure environment. It's optimized for automation and can be used in a DevOps pipeline. You can use Azure CLI to create and manage resources such as virtual machines, storage accounts, and web apps, among others.

Before using Azure CLI, you need to authenticate with your Azure account. You can do this by using the az login command, which opens a web browser for you to sign in with your Azure credentials.

Azure CLI Usage Pattern

$ az [group] [subgroup] [command]

Example – to create a new resource group

$ az group create

Installing

$ brew update && brew install azure-cli

Verifying

$ az --version

azure-cli                         2.26.1 *

core                              2.26.1 *
telemetry                          1.0.6

Python location '/usr/local/Cellar/azure-cli/2.26.1/libexec/bin/python'
Extensions directory '/Users/kenanhancer/.azure/cliextensions'

Creating Azure Function App for Python with Azure Functions Core Tools CLI

How to install Azure CLI and Azure Functions Core Tools CLI with Homebrew
Azure Functions Basics

We cannot specify the Python runtime version with FUNCTIONS_EXTENSION_VERSION. The FUNCTIONS_EXTENSION_VERSION setting is specifically for specifying the version of the Azure Functions runtime, not the version of Python.

The Azure Functions runtime is the host that runs your functions. It's a separate concept from the Python runtime. Each version of the Azure Functions runtime has a range of versions of Python (and other languages) that it supports, but you can't use the FUNCTIONS_EXTENSION_VERSION setting to choose a specific Python version.

The version of Python that's used in your function app is typically determined by the environment in which the app is running. When running locally, this will be the version of Python that's available in your local environment. When running in Azure, the Python version is determined by the configuration of your Azure Functions host.

If you want to specify a Python version for local development, you can do so using a Python version management tool like pyenv, and creating a .python-version file in the root of your function app project. For deployment in Azure, you specify the Python version when you create the Function App.

Remember to check the Azure Functions runtime support for your chosen Python version. Azure Functions 4.x runtime supports Python 3.7, 3.8, 3.9 and 3.10 for now.

Prerequisite check for Python

$ az --version
$ az login
$ func --version
$ python --version

Create and activate a virtual environment with virtualenv package manager

virtualenv (for Python 2) and venv (for Python 3) allow you to manage separate package installations for different projects.
