I am adding the relevant references first

https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-python

https://learn.microsoft.com/en-us/azure/azure-functions/create-first-function-cli-python?pivots=python-mode-decorators&tabs=azure-cli%2Cbash

follow the upper links to create an environment

you can use visual studio code (mac version to build the environment)

@Brian Huimin Kang (US) Thanks for reaching out.

Have you review the below document for Visual Studio for Mac 7.5

https://learn.microsoft.com/en-us/visualstudio/mac/azure-functions?view=vsmac-2022

You can try below steps:

Install Visual Studio Code on your Mac if you haven't already done so.

Install the Azure Functions extension for Visual Studio Code. You can do this by opening Visual Studio Code, clicking on the "Extensions" icon on the left-hand side, and searching for "Azure Functions".

Install the Azure Functions Core Tools. You can do this by opening a terminal window and running the following command: brew tap azure/functions brew install azure-functions-core-tools@3 This will install version 3 of the Azure Functions Core Tools, which is compatible with Python Azure Functions.

Create a new Python Azure Function project. You can do this by opening Visual Studio Code, clicking on the "Explorer" icon on the left-hand side, and clicking on the "Create New Project" button. Select "Azure Functions" as the project type, and then select "Python" as the language. This will create a new Python Azure Function project with a sample function.

Run the function locally. You can do this by opening a terminal window, navigating to the project directory, and running the following command: func start This will start the Azure Functions runtime and allow you to test your function locally.

Test the function. You can test the function by opening a web browser and navigating to http://localhost:7071/api/<function-name>, where <function-name> is the name of your function. This will invoke your function and display the output in the web browser.

In case if this is not supported then you can reach out to the azure function core tool team here.

@Brian Huimin Kang (US) Python worker does not support running on Mac M1 at the moment. There is multiple issue that are tracked in below links and the official document also cover it with the workaround: https://learn.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=v4%2Cwindows%2Ccsharp%2Cportal%2Cbash#x86-emulation-on-arm64

Brian Huimin Kang (US) As described above, ARM 64 is currently not supported for Python 3.9, 3.10 versions. However, we have added the support in 3.11 (preview) which we are targeting for release in the upcoming days (current ETA this month subject to change; follow https://azure.microsoft.com/en-ca/updates). Meanwhile, you can follow the workaround as described by MayankBargali-MSFT such as X86 emulation.

Our product team is looking to add support for existing 3.9/3.10 versions with the priority. Sorry for the inconvenience caused and let us know if you have any other questions.

Thanks for all your answer. Sorry for late reply

I find a way to work out this issue. It might only work for my case. But for others, it might give you some insight.

Steps:

install miniforge3 and then create a x86_64 environment
install azure-functions-core-tools with npm
create the .venv environment by leveraging the x86_64 env
update /usr/local/lib/node_modules/azure-functions-core-tools/bin/workers/python/worker.config.json :
```
  "defaultWorkerPath":"%FUNCTIONS_WORKER_RUNTIME_VERSION%/{os}/X64/worker.py",
```
1. when launch your python azure function, please activate .venv env first .

@Brian Huimin Kang (US) I like the flow of this answer - One thing I'm running into and wondering if you were able to get working - the func command is not available after doing the npm install. Seems the only way I can get the func command to work is with homebrew, which always tries from the arm architecture. Any thoughts?
