Updated python example

[j-antunes]

I tried the python example and it is not working out of the box. The main issue that I was facing is:

google.api_core.exceptions.BadRequest: 400 GET https://storage.googleapis.com/storage/v1/b?project=test&projection=noAcl&prettyPrint=false: Invalid project number: 0. Project id: 0 is invalid or not found

I think the issue has to do with not setting the api_endpoint for the docker container.

The solution is to add

    client_options={"api_endpoint": "http://localhost:4443"},

Apart from that I added some instructions as to how to run this example.

The instructions on how to run the example can be derived from the CI script that executes the example in GHA. Can you update the comment to reflect that and undo the client_options step? Otherwise, this breaks CI.

@fsouza - I followed you suggestion and update my example.

I added this line
os.environ["STORAGE_EMULATOR_HOST"] = os.environ.get( "STORAGE_EMULATOR_HOST", "http://localhost:4443" )

That should help to make this example more clear without breaking your CI. This tries to get the value of the STORAGE_EMULATOR_HOST environment variable. If it doesn't exist, it provides a default value of "http://localhost:4443/".

When you run your CI, you set this value, so it will use localhost:8080, if running just the python script with the instructions it will set to localhost:4443

Thanks!
