When following the instructions for Azure Functions local development in Python using Command Line Tools on Ubuntu 20.04; on running func start the following error appears:

which is resolved by commenting out half the annotation as in the following example:

@app.route(route="HttpExample") #, auth_level=func.AuthLevel.Anonymous)
def HttpExample(req: func.HttpRequest) -> func.HttpResponse:

@matyjas Thanks for your feedback! We will investigate and update as appropriate.

@matyjas Instead of commenting the below line of code in function_app.py file.

@app.route(route="HttpExample") #, auth_level=func.AuthLevel.Anonymous)
def HttpExample(req: func.HttpRequest) -> func.HttpResponse:

Please try the any of the below work around to run the function without any issues.

Work Around 1: 

@app.route(route="HttpExample", auth_level=func.AuthLevel.ANONYMOUS)
def HttpExample(req: func.HttpRequest) -> func.HttpResponse:

WorkAround 2:

app = func.FunctionApp(http_auth_level=func.AuthLevel.ANONYMOUS)
@app.route(route="HttpExample")
def HttpExample(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

Also, I see there is an active issue related to this which is reported in Azure function tool github repo here #3651.

I would suggest you follow the latest discussion over there. We will close this out, but if you feel you need more information, please just let us know.
